  1. Some more slug setups and ideas.

     

    First is USS brand sabot that European cartridge has, without

    locked base, a discarding 12ga sabot, with .629" brass slug.

    It is as accurate in rifled barrel as its locked on base

    counterpart, in smooth barrels. Up to 750 gr brass slug

    I tested. 3 shots in an inch, 30yds.

    Shown with BPI powder cup seals.

     

    4uss.jpg

     

     

     

    2nd is the USS slugs with locked on base for comparison.

    With corresponding length cases they were designed for.

     

    eucart.jpg

     

     

     

    3rd are heavy solid tungsten slugs, the smaller .580" cal and

    1200gr, the bigger ones .660" cal and 2200 gr.

    A guy in Southern MI made a few for me to check out. Now these

    too hard to fire fullbore, damage rifling, must be in plastic.

    These are just what the super heavy slug guys might like.

    4th is a 1000gr 58cal tungsten slug in a 12ga REM style

    58cal sabot. Notice how short it is for being super heavy.

  2. Some more sabot and slug ideas, discarding types

    and locked on base types.

     

    First picture of 20ga Buckhamer pulled apart. The bunch

    I have were pulled apart, the slug won't lock back in

    tight, into the base.

     

    buckha20.jpg

     

    Second is various 20ga sabot/slug ideas some using

    buckhammer sabot bases that a bunch of 458 cal lead

    slugs and jackted slugs I have, lock into real tight.

    The 458 lead ones are 400gr, jkt are 350gr.

     

    And I got some empty SPW 20 gauge sabots, and 20ga

    Buckhammer slugs lock into them real tight.I have

    many of these slugs. These slugs are 440gr.

     

    Also is 3" 20ga FED factory sabot shell and one of

    discarding sabots out of the case. Also a 3.5" 20ga

    Hastings 3.5" load with black locked on base sabot,

    and sabots out of the case and couple 20 brass

    3.5" RMC cases.

     

    20sabsl.jpg

     

    Next is variety of 12ga sabots with 50cal slugs

    in them.2 white and the pink sabot are FED, The black

    is Hornady, With a 50cal long bullet .

    The grey, is a BPI with .504" cast 440gr slug.

    I wish the BPI was full size like the others

    and fit rifled barrels tight for accuracy.........

     

    12ls50.jpg

     

    Last 12ga SPWs from Slug-R-US(30 cents ea) with various

    50 cal slugs locked in tight, and shown with one out of

    a factory load, the dark colored one. 50cal 385gr

    Great Plains ML slugs lock in perfect for a lighter

    loading. Other ML slugs will do and a few of

    the Dixie Gunworks 50cal slugs lock in also...Ed

     

     

    12spws.jpg

     

  3. Here are some more sabot/slug and loading concepts.

     

    First is Alcan 2.75" paper case with Dixie 600gr slug,

    with the side of the case crimped into the relief/lube

    groove of the Dixie slug.The groove in the Dixie isn't

    quite as deep as the groove in the Fosbury slug shown

    in earlier post, but still seems to crimp fairly tight.

     

    alcan.jpg

     

    Next are various slugs in 12ga REM sabots that take

    57 cal slugs and bullets.Those sabots are from the REM

    Accutip loadings. In picture you can see one of the

    REM 385gr jkt bullets they use. Also is sabot

    with 20ga cast Lyman. On right sabot with hardcast 585 cal

    640gr lead bullet, the ones I use in my 585HE wildcat

    case. I sized it down a little, perfect fit.

    Also the .575 cal Dixie Gunworks lead slugs will do.

     

    Also shown is a long pointed 55 Boys bullet in one,

    fairly tight fit.We cut back .3" of bullet off so it

    fit for length in sabot and is 750gr.

     

    12ls58.jpg

     

    Third are 3.5" brass and plastic with the REM sabot and

    the 750gr pointed slugs in them.In all the sabot work we

    and others have done, trying to get accuracy and high

    speeds together, maybe there is such a thing as too

    much plastic. IE, sabots too thick on the sides if doing

    50cal or smaller in 12ga sabots, for heavier slugs

    at high speeds. Thinner sides may discard more evenly at

    the greater pressures and violence of high speeds.

    Thin sides may have less give so that sabot grips slug

    better to impart spin in rifled use. Example in

    smoothbore use is the USS slugs, where the brass slug

    is .629" with thin discarding petals that have proven to

    be very accurate. And with both reasonable priced sabot

    offerings the last few years being undersize, accuracy

    problems, etc, maybe time to try something else.

     

    Got to find whole bunch of these sabots. Are these pictured

    12ga REMs the only 58cal ones around? I can't find others,

    and maybe we can find where these are made. As I have

    huge numbers of the 585 slugs, which by the way I think

    is best hunting combination, without extremely heavy slugs

    which suffer for the speeds needed for longer range use.

    It is hard lead, good for big game.And my guy can make many,

    many more if needed whether for 585HE rifles

    or in sabots if we can find some.ED

     

    55sabot.jpg

     

     

  4. Some more slug and sabot ideas folks are doing.

     

    First is a long pointed slug with locked on base,

    It goes to target with base,can work smoothbore.

     

    paraklese.jpg

     

    Second is picture of Hexolit sabot base slug

    with petals expanded, sure would make bad wound.

     

    hexolit.jpg

     

    Third shows a variety of Gualandi slugs you can

    get for reloading, and we're finding that these

    locked base slugs, Brenekke/USS style slugs, are

    giving good accuracy in smooth barrels which can

    save when doing heavy barrels.Weights shown in

    grams, get our weights in grains multiply by 15.4..Ed

     

    gualandi.jpg

  5. First picture is an RC4 brand slug I see is available

    down under. It has locked base like Brenekke.

    And locked on without discarding petals, like US-S.

     

    And 2nd picture is a group fired with RC4 slugs

    by fellow on NitroExpress forums from a good

    double 12ga, 2 left and 2 rights at 25yds.

    This shows the possibilities of working with smoothbores,

    rather than not trying to make them work.

     

    3rd picture is a discarding sabot base slug, and with

    four discarding sabot carriers, with centered

    penetrating solid bullet, from France.Ed

    In earlier thread I mentioned the long brass 28ga case

    we setup. Well here is picture of a revolving 28ga

    we will try to get later on and put in heavy barrel

    and longer chamber and use brass 28ga cases.Ed

     

    SCJ28B_011.jpg

  6. Here are couple more pictures of longer bullets

    in sabots, loaded in plastic cases, with the

    roll crimp down against the sabot. Both are

    ideas tested by European Cartridge in Greece,

    who make the US-S slugs. Both longer bullets

    pictured have the locked on base that their

    other US-S slugs have, for smooth bore accuracy.

    2nd picture shows a deep hollow roll crimper

    for doing slugs like these.Ed

     

    pushin.jpg

     

    usslongnose.jpg

     

     

    We also had RMC make us a long brass 28ga case.

    It is 3.25" long as shown in picture. They could be

    3" or whatever you would want. The 550 Mag rifled barrels

    are perfect bore for them, and we did one

    in a Mossy 695 bolt gun, 2nd picture...Added heavy barrel.

    It is shown next to a 505 Gibbs brass

    case 1st picture to show that it isn't a puny case.

    And chamber still fires plastic 28ga like the

    new Brenekke slugs just out.Ed

     

    28fhg.jpg

     

    moss28d.jpg

  7. Here is picture of 4 long cases, top being a Rocky Mtn Cartridge

    3.5" turned brass 20ga. Next a RMC 3.5" turned brass 12ga.

    3rd down our 3.85" 12ga FH we made from BMG brass. Bottom

    a RMC 3.85" turned brass 12ga FH case.

     

    rip4.jpg

     

     

    Next picture shows one of the old ways they locked slugs

    into paper cases. Many old slugs had a wide deep groove

    which made it possible to crimp that way.

     

    bodycrimp.jpg

     

     

    Next pictures shows bullet jackets made from a copper tubing caps.

    Caps are the ones they solder on to copper pipes, and they made

    a die and punch to form them to a good nose shape and

    size. Then they fill them from rear with lead.

    Example; 1/2" cap does 700cal and 12ga with

    right dies and punches.

    Last the 2nd gun we put the 585HE long belted case in,

    a Ruger 77 bolt action. it has a heavy 585 cal barrel,

    and it is a real strong action....Ed

     

    585ruger.jpg

     

  8. I'm glad it got moved here where it fits in better.

    Thank you moderators. I could throw in a Garand, as

    a big bore, as guys have made them in 458s,

    and one would do for my 585SHE.

     

    Well the 2 3/4 inch brass case with 600 gr slug will do

    over 1800 in brass case. That is over 4300 ft lbs.

    Very interesting to shoot by guys who have only

    shot slow factory 1oz slug loads.Ed

  9. We are always looking for way to shoot 8 and 10s

    using easy to get components,cheap, without buying

    loaded rounds for big bucks, if available at all.

     

    In 8ga falling block, plastic case got 930gr hollowbase

    slug to 2300, It is a slug for 10 ga that we expanded

    base a little to fit tight in 8ga wadcup. On the left in

    picture. At 30 yds 3" group. Just with open sight,

    About like the 10ga sight bead. There is enough hollow in

    the base it flies pretty good from 8ga smooth barrel.

     

    Along same line, in my 10ga 32" smooth bull barrel with a

    750 gr .69cal hollowbase Dixie MZ slug in VP100

    10ga wadcup about same speed and same accuracy.

    Nice to just get a box of slugs that is in stock,

    and a 2 cent cent wadcup and Fed 3.5" 10ga plastic cases

    and be shooting cheap.And the cases roll crimp nice

    down to these slugs...

     

    8gawad.jpg

     

    A different, interesting style, of 12ga slug, from Russia.

    First picture loaded round, in plastic, roll crimped.

    Second, two types of slugs they have on the same base.

    Base for rifled barrel, little smaller diameter than the

    front. Looks like the roll crimp locks against

    the edge of the base. Neat idea, and it could have a

    flat meplat slug on the front of the base like

    the US-S brass slugs from Greece are on the

    plastic bases, that I have here. They must use a crimping

    die with a deep hollow up in the middle. We have thought

    of taking a roll crimper and putting a deeper recess

    in middle to load longer nose slugs further out so as to

    have more room for our slower powders...

     

    rucase.jpg

     

    ruslug.jpg

     

     

    Here is picture of a great sizer for expanded plastic

    cases, a MEC Super Sizer. It operates with collets. Sizes

    cases better than factory. Has the power to shrink

    expanded basecups. 2nd picture is the roll crimper tool

    in drill press, it does plastic cases as good a roll crimp

    as the factory does.You can see couple we crimped

    behind press base in picture...Ed

  10. These big bores are huge fun when they are loaded like ours, so that

    when they go off it sounds like a tank gun. And being able to do it

    in economical guns, instead off guns costing an arm and a leg,

    really makes it fun. And many guys like autos and pumps.

    There are no big bore rifles in sporting autos to be had

    reasonable, or at all, but we have big auto shotgun calibers, and

    Saigas as well as all the others makes it easy. I have a 3.5"

    12ga Khan auto, of the grandson, to test loads, and it is a real blast

    with the US-S saboted 570 gr slugs at 2000. And if it had

    heavy barrel it would do about 20% faster.40% more energy. Ed

  11. Just trying to get info out and see if we can make more

    big bore nuts. Like planting seed and we hope others

    will join in with ideas. We have nothing to

    sell, the info is all free.Is there reason why some Saiga

    owners wouldn't be interested in big bores, anymore

    than a big bore nut wouldn't be interested in Saigas ??

     

    Some more slug experimenting and developement.

    Here are pictures of the full bore Lee Key Slug

    we had a guy cast. He took Lee Key mold and machined

    it out to cast a .729" full bore slug.

    The original Lee mold makes slugs smaller diameter,

    so that they fit in a 12ga wadcup.

    Slugs are hard cast alloy to take high speeds..

    In picture is two MRC 2 5/8" brass 12ga cases with

    slugs in them. These slugs with those brass cases are

    being tested first in rifled barrels in a guys 1887 WIN,

    where they needed short combination to feed from tube.

    These slugs have real good shoulder step to

    roll crimp against when used in plastic cases.

     

    These first ones are 500 gr.The guys are reworking

    another die to get the weight up to about 600gr,

    that some of our the brass case guys want to use.

    So many guys like the 600 gr size, but these with

    the partly hollow base allows them to be longer,

    for a little more stability,if used in smooth barrels.

    Lee molds are not a real high price so it isn't

    a bad deal to get them and change them.

     

    Some newer slug ideas coming around. First is Brenneke,

    a locked on base ounce slug, in sabot at factory speed of

    16-1700 or so in 3" plastic.Really go in our 3.5" loads.

    Brenekke has had full bore slugs with lock-on seal and

    cushion, but this new appliction putting them in a sabot.

    Picture #2

     

     

    Third is Dupleks, steel slug riding on a plastic band,

    penetrates very well. About 1 1/8 oz.And no steel touches

    the bore only the plastic.Should have good penetration

    witout breaking apart.These are front heavy will get

    fair accuracy in smooth bores.

    Monolit_32_picture.jpg

     

     

    A new slug from the EU,a new 300gr US-S slug with locked

    on base, discarding petals, by European Cartridge. Accurate

    in smooth bores, Using the same idea as their all brass slugs

    we showed above with locked on base, and discarding front petals.

    Only these are mostly aluminum to get a lighter slug combo.In the

    first picture.In 3" plastic they load to over 2100 with shotgun

    powders. In a 3.5" plastic and our slower powders

    we can get 2800. 2nd picture some results of penetration tests

    in a sand bank they did. The brass centers penetrate like the

    all brass ones they make.They are reporting 2" groups from regular

    barreled smoothbore pumpguns at 50 yds with scope.Ed

    p1010009zh.jpg

  12. Some more stuff from the old days---

    First is picture sectioned Explora case and slug, showing how

    they kept weight down so that it could be stepped up in

    speed in older doubles, that didn't have real heavy barrels.

    These guns had short section of rifling at the end

    of the barrel or shallow rifling. THis allowed more speed

    than old foster slugs which flattened the trajectory,

    and along with rifling spin, allowed for longer range shooting.

     

     

    Second picture from Greener book here, is of older 4 and

    8 gauges.And you can see videos some of these great old

    guns on Youtube.

     

    Third picture shows steps of making 4bore case, one inch bore,

    from 20mm. 2nd in picture is case with base turned and swaged

    to size which leaves base smaller than rim, for rimmed case.

    Then 3rd case has top expanded to take 1" diameter slug.

    last shows the thickness and strength of finished case.

    This case matches the turned 4bore case that Ken Owen had made

    for the 4bore doubles he built.

     

     

     

    explora.jpg

     

    gr3.jpg

     

    make4.jpg

     

     

    And more from the old days, here is picture of

    a variety of slugs being promoted and used a century ago.

    And 2nd picture Paradox cases old and new.Bottom one is a

    more modern version sold by H&H for slug hunters.

     

    3rd is what a 4bore slug, if stop framed so to speak, would

    look just leaving the muzzle of the 4bore falling block

    we built. Some 4bores were used in the old days but they were

    poorly stocked and balanced for taming recoil. Ours with thick

    pads, thumbhole stock, proper balance with 1500gr

    slug at 2000 all our guys here can handle just fine..Ed

  13. What we are doing in getting more power from shotgun calibers

    isn't super new or completely novel, most just

    modernizing and improving older ideas..

     

    In the early days; in my Greener's book he states that

    gun with a rifled choke section of the barrel, called

    12ga paradox shotgun/rifles, with slugs, heavier powder

    charges than shot loads, could hold what amounted to

    about 5 inch pattern at 100 yds.

     

    And still had over 1800 ft lbs energy at 100yds.

    And that is with guns with lighter, thinner barrels

    than we have today, so our work is a good extension

    of what the early big bore guys did.

     

    And then 4bore for guys liking a big challenge, 4th picture.

    Thanks to rattler on 24hr forum for the first 4 pics.

    Continuing-Many have success with all kinds of high-power slug designs and

    with extra power, have pushed the reliable range of 12ga slugs/bullets

    from 75 yds to 150+ yds. Even in the old days. Here is picture from a 1926

    Manton catalog showing, 1st picture, many brass case old time slug loads.

    Notice the 20 bore and 12 bore ones with pointed slugs, seems

    as ideas to hotrod 20s and 12s are old hat, not quite as strong as 12ga FH

    but as strong as some factory hotrod loads now ....We can do more

    now due to better guns, powder selection, and accumulated research.

    Picture #1 from lancaster and CptCurl on Nitroexpress.

     

    2nd picture is from the Greener book, of double 8ga elephant guns.

     

    2rd is picture of an early falling block for big bores

    called the Field I think. Looks like some other

    side levers, looks like lever works forward.

     

    And speaking of falling blocks 4th picture is the

    start or 'fixins' so to speak for the next step

    up, for our 2bore. Same design as the 4 and 8

    bores only wider.

     

    We are now getting 2.25" OD barrel reamed

    out to the two bore size.

    And a square hole for breach block done

    in that hunk of 4130 steel.Ed

  14. Some more gun info. Here is picture of a nice, large diameter

    action a fellow built, for big bore use.Nice beautiful machine

    work, He put a 700 short case in it. He called it 700WTF.

    It would do 12ga, 16ga, 20 ga, etc.

     

    Second is the 8 bore we just made on falling block. It is

    chambered for now for the 8ga 3.3" heavy duty plastic

    case that we use. That we get by swaging the belt down on

    the new 8ga kiln cases, that BPI and Precision Reloading sell.

    The chamber fires old original 8ga cases also, but a regular

    kiln load not swaged, won't chamber, a safety factor for guns not

    as strong as the falling block. Guys in the UK gave me the idea

    of swaging down the belt on kiln cases, as they did it

    to get cases for their old 8ga doubles.

     

    Third is the Savage 210 we put a 700 cal barrel in and made it

    a 700NE. The 700 NE has same rim diameter as 12ga, but a

    smaller base, ,020" smaller, Handles the loads fine, as its

    factory loads are the same as our top loads in the Savage

    with RMC 3.5 brass cases. Before that I had my 700H 3.25"

    belted case in it. Worked great.

     

    4th- we made a 28ga FH, a brass case 3.25" long that

    RMC made for us. The chamber still fits and fires shorter

    28ga plastic cases.Here is one in picture with a 505 Gibbs to show

    the size and potential. I put first one in a Mossy 695 bolt gun

    with a heavy rifled barrel. The 28ga rifled is same groove

    diameter as the 550 magnum, so same diameter slugs work.

     

    5th are couple of our 12ga FH cases guys shortened for

    short actions, less recoil. Left are 2 inches,right 2.25"

    and some have shortened them to 2.5" for use in

    guns that will feed loaded 3" plastic. The 3" loaded plastic

    and 2.5" brass with slug are about 2.7" overall..

    If you folks have questions we'll help if we can.Ed

  15. Just passing out info to see if we can make more

    big bore nuts, by planting a little seed, so to speak.

    Wehave no business to sell stuff just doing research.

    Some more gun info about what others around the world

    are doing with big bores. First is a 4bore Tula pump

    gun, made in Russia. A few guys in the US have them.

    They are smoothbore and .938" bore. They used a short

    3" long plastic case, and we helped some of the

    owners get a run of brass cases by Rocky Mtn Cartridge.

    Big Al, a poster on the AR Big Bore Forums owns one.

    Our 4bore case is a full 1" bore 4.05" long.

    Many early 4bores for shot were set up with .935-938"

    smooth bores.

     

    Second is a bolt gun a guy in Europe did in 1" bore

    using 20mm brass expanded, ending up for

    headspacing, a small shoulder. It is full length like

    ours, instead of shortened like other pipsqueak ones.

    3rd is our big and small falling blocks, big one

    the 4bore we made and other a FBW Model L in 585HE.

    Both stocks need finishing in these pictures

    and metal surfaces has to be finished...I'm not a

    fancy, finish smith and to busy experimenting,

    to get everything real fancy.

     

    4th is a 20ga FH 3.5" chamber break action. It is a

    CBC and we monoblocked in a heavy long 20ga barrel.

    5th is a Mauser 12ga GEHA conversion, that had real

    light barrel and cracked stock. We put the extra

    Savage 12ga 24", rifled slug barrel we had in it, and

    used the strong Savage plastic stock. Still has original

    3" chamber and we test our slow powder 3" plastic loads.

    Great load with full bore slug, is 600gr Dixie, using

    90gr IMR4759, going 1800. This load was lab tested

    and verified for speed and only runs plastic case, magnum

    shotgun pressures.

    More info on cases, first is our cases where we put in a

    bushing to use shotgun primers. Also some of the guys

    shorten the cases for use in 3" and shorter chambers.

    Magtech makes 2.5" 12ga drawn brass cases that guys

    are reloading for use in short actions, like 1887 leverguns.

    2nd is 8ga plastic cases we use, the left 2 are

    REM and clear is WIN. These can be gotten at BPI

    and Precision Reloading. We use roll crimp on

    these for slugs and sabots.

    1100gr at 2000 is a good load. 9 triple ought buckshot

    is a good load. Totals 630gr for the 9, goes 2500

    if you want hairy load.

     

    3rd are 8 and 10 ga hard cast slugs with hollowbases, we use.

    4th is some of our wildcat cartridge stuff, my 585HE cases,

    die sets, and reamers. Dies are by CH4D, reamers by Manson.

    5th is our 585HE in two break actions, a CBC and NEF.

    Both set up by mono-blocking in 585 heavy barrels...Ed

  16. Quite a few have wanted doubles in our 12GA long case.

    Rob is doing one on a big 10ga Zabala double,with Greener

    crossbolt lock. He is replacing 10ga barrels with heavy

    12ga rifled barrels, mono-blocked into the 10ga breaches

    by threading them into the breach sections.

    First,2nd,3rd pictures. He is now building and getting

    barrel ribs done and the gun regulated.

     

    4th picture is my 700HE in a Vulcan bolt action.

    5th is the 6gal water pail from the Youtube video, atomizing.

    The pail was heavy plastic, full and sealed tight.

    That was 12ga 600gr hollow point slug about 3000 fps.

    CASES-1st is comparison of 12ga FH brass cases, with ours on the

    left we made using bmg brass, and 3 on the right that

    are of a few we found already done in 12ga size, that is

    as long as ours.RMC makes them long as ours and any length needed.

    2nd is our long case next to short one.You can see how much

    thicker and stronger our case is.

     

    3rd is a slug made for rifled, for use in 12ga wadcup, and it

    being 16ga size works in our 16ga FH case also, as shown.

    4th shows 20ga RMC cases and dies we have found for them.

     

     

    5th shows 1500gr 4bore slugs a guy cast for me and cases.

    These are hollowbase, as our 4 and 8 gauges on the falling

    blocks, are smoothbore. Top loads with these 25-2700.Ed

  17. Now some info on cases and slugs

    The 50 BMG brass can be made into some real

    great cartridges, our 12ga FH, shown first, showing

    cases with rim turned off and threaded; and the 12ga rim

    pieces to be screwed on, with finished cases shown.

    And 2nd making my 700HE showing original BMG case,

    case with belt only, and then expanded out to 700cal.

    This makes a super strong big bore case, as I have

    fired some 25 times and case is still good.And

    it in my big Vulcan bolt gun gets a 1000gr to 3200.

     

    3rd picture shows our 4bore/ga case with slugs, and

    the 20mm case we make them from. They match the 4bore

    turned cases that are used in the Ken Owen doubles.

    4th the Rocky Mtn Cartridge, 12ga turned 3.5" cases

    with variety of slugs and sabots.In picture first loaded

    one is BPI sabot, then 730gr Dixie, then 600gr Dixie,

    then RG Henson's solid nose and his hollowpoint.

    RMC can make cases any length and any gauge.

    5th shows a 12ga FH and 10ga FH we made using steel

    basecups taken from 12 and 10 ga cases. We turned down

    bases a few thousands of the original brass cases

    and epoxied the bases. Used BMG case s for 12ga and

    50cal Russian for 10ga.This research came from a

    another forum poster, like over half of what we do.Ed

    More pictures of 12ga slugs and saboted slugs.

    1st The US-S sabot/slug, with the green locked on base,

    along with others.The US-S slug is nearly as accurate

    in smoothbores, for which it is made, as sabots are

    in rifled. those pictured are heavier than most other

    brands of saboted slugs.

     

    2nd a Jacketed 730gr by RG Henson and a hard,heat treated

    600gr by Dixie Slugs in FL, both full bore slugs,

    3rd a BPI sabot with hardcast 440gr, .504"

    diameter slug. BPIs were intended to use .500" bullets

    used in 500S&W, the little larger ones we use seem

    little more accurate.Makes tighter fit in rifled barrels.

    4th other sabots we tested , 5th brass turned slugs

    and there are many other slugs/sabots we'll show..Ed

  18. Videos, Youtube- blowing up 6gal pail of water -"Grandpa's Cannon"

    "Grandpa's First Shot" 12ga FH -- 610gr HP at 2800-3000.

     

    We get asked about legality and whether these big cartridges

    are DDs. First of all; all shotgun calibers over 50cal are exempt from

    being classified as DDs under Title 18 GCA Section 921....

    And it doesn't matter what exciting or promo name we call them,

    the barrels are still marked for gauge. They can be called 12ga 3 Inch

    Super Magnum, 12ga Goose Magnum, 12ga From hell, 12ga 3.5 Express,

    12ga Hammerhead, etc, they still are a 12ga case of some length.

    And length doesn't matter as long as shorter cases, with straight

    sides, and same 12ga(or whatever gauge)base size fit and fire in

    longer chambers. IE; 2.5, 2.75, and 3" firing in 3.5", and all of these

    firing in our 3.85" longer chamber. IE; you can't take 37mm cannon

    shell and neck it to 12ga and have an automatically exempt 12ga

    cartridge, as other shorter 12 gauges would not fit/fire in chamber,

    and you'd have to get it exempt as sporting. How-

    Under the same Section any other over 50cal non-shotgun

    cartridge can be classified as Exempt For Sporting Use by

    applying for the exemption, like I have done for my cases,and many

    others(JDJ-AHR-Etc) have done, as well as cases already sporting

    from the old days. Now as for hunting rules in shotgun areas,

    game depts may say that you can't use long range spitzer bullets

    but must use traditional blunt slugs, for safety. Hunting rules are

    varied all over the place.Ed

     

  19. More history of firsts, in our 12ga FH and big bore work.

     

    The first gun of mine to have this case was

    my Savage 210 in first picture with a regular style

    heavy stock. Later changed to thumbhole stock.

    I changed barrel to heavy bull barrel and

    chambered it for the 12ga FH 3.85" long case.

     

    Second picture is the first NEF 12ga Ultra that we put

    the first 12ga fH case in. I only had to lengthen chamber.

    The same gun now has long barrel and thumbhole stock.

     

    Third picture is first NEF 10ga heavy barrel that we put

    the 10ga FH in. Gun came with long 30" heavy barrel.

     

    Fourth picture is the first 8ga test gun we built using the

    super strong 8ga kiln cases with the belt step swaged

    down. It is an Enfield that we reamed out to take the

    case, like the 12ga Mauser 12ga conversions were done.

    And we added extra rear bolt lugs for strength.

     

    Fifth picture is the 1st gun my 585HE was put in.

    It is an Enfield and gets 750gr bullet 2700 fps.

    585enth.jpg

     

     

    And in the vein of old time gun actions, of which are various falling

    blocks, we like them also for the hairy big bores, like the 8bore and

    4bore ones we made over the years, that are pictured above.

    Following are 3 pictures of various parts and processes of making the

    action, using easy to get small parts, lever, trigger, hammer, etc,

    and the action block, breach block from steel blocks in 1st pic.

     

    Last 2 pictures are the FBW brand falling blocks, one which is the

    Model L that we adapted to the one piece stock and the other is the

    smaller Model S with regular two piece stock. Both are set up with

    my 585HE. I can run full pressure in the 585.

     

    The Model L, I can switch to a 20ga barrel, 600NE barrel,

    and my 700HE using moderate loads. Last pic is Model L with

    thumb hole stock, and my 585HE case in the action..Ed

  20. I'm visiting here to talk about the 12ga From Hell and

    other developements it has led to.Nice site you folks have.

    I'm with a group of experimenters passing on the years of

    info and pictures to all gun nuts around the net, about

    12ga From Hell and other big bores. We have posted some

    round the net about our many ideas we have implemented for

    12ga,10ga,8ga,4ga,28ga,20ga,16ga, and my 585HE/700HE wildcats.

     

    The idea for the 12ga FH, and the first gun built for it,

    was Rob Garnicks on the AR Forums. In the first picture,

    a heavy duty Borchardt falling block. He has gotten

    1000 gr to 3000 fps in this, a high pressure action.

     

    Then I and others joined in and set up a big variety

    of guns for the case. The case, a brass case 3.85" long,

    made from BMG brass expanded out with straight sides,

    to take 12ga .729" dia slugs and a 12ga size rim added on.

    Also we get turned brass cases from Rocky Mtn Cart of that

    length and shorter. Many guys used 3.5" cases, as standard

    reamers are available, and 12ga 3.5" guns are available,

    so that they could shoot 3.5" plastic also. Our 3.85" chamber

    and 3.5" will shoot any of the shorter cases.

    In our work we found ways to get over a third more velocity

    in shorter plastic and brass cases using slower powders

    than regular fast shotgun powders. We reloaded fast

    rifle powder, IMR 4759, IMR 4227, in larger amounts

    and got 600gr hard lead slugs over 1800 fps in 24" barrels,

    and were lab tested to be at or under magnum shotgun

    pressures that are used in factory 3.5" loads.

     

     

    More pictures, the 2nd showing long brass 12ga FH case with

    regular 12ga case. Other 12ga FH guns are next,3rd Nef Ultra

    heavy barrel with length added, 4th Nef 8ga made by boring

    out heavy barrel 10ga, 5th FBW falling block,my 585HE belted

    case.The FBW has a 20ga 3.5" extra barrel also.

    .And we also worked with 8ga,4ga, in falling blocks, 20ga,16ga

    in break actions, and my wildcat 585HE,700HE in various actions.

     

    6th picture is our big cartridges from 2 bore on down, in

    order-2bore- 4ga- 8ga- 10ga- 12ga FH- 700HE--700H 3.25- 30-06..

    7th picture is 4bore falling block we built on our design.

    Our 4bore is 1 inch bore.We also helped in getting the barrel

    threads larger in the new large MRC PH bolt action to fit our

    cases like the 700H 3.25" shown in 8th picture in MRC.

     

    9th picture is an 8bore bolt gun a guy on another forum built

    from scratch.Last is Savage 210 that Bret in MN set up with

    heavy barrel and a recoil reducer put into the hollow stock.

    Shown with boot off so you can see the build. He has gotten

    saboted 500gr slugs over 3000 in this.We will post a bunch

    more info and we welcome your ideas and help. And we'll give

    all the help we can to folks ..Ed Hubel
