hubel458 6 Posted November 10, 2015 Author Report Share Posted November 10, 2015 Here we kill two birds with one stone so to speak, Best case sizer is the MEC Collet Super Sizer and it can double as a case holder when we roll crimp. Much better hold than the ones made to hold cases for crimping, that cost a lot. Save cost of a holder, plus have best sizer around Here is couple different setups our guys checking for our 585HE in a long, Lawton Cheytac action. First laminated thumbhole stock. Second in a Hogue Compstock. The action can mount a scope rail like shown on the table in 1st picture or a receiver sight in 2nd picture. The scope rail is a piccatiny type. The stocks used were wide ones for REM long actions, just add recoil block ahead of recoil inleting for the longer action, drill new screw hole Open the stock forward to original bolt hole for longer cases and mag. About Enfields for our case, one of my favorites, Some don't like the sporterizing, welding bottom metal straight. Many think straightening is a huge job needing special jigs. Easier just use one being added on for a jig with a bolt, to weld on the straight extension, Do top weld, then cut old extension that is under off with a thin cutting wheel, then weld bottom. When we bolt the short piece on the one we are straightening, we grind the short slant off so the added piece lays on there flat. The one you cut off can be used as the top extension for the next one!!! Just keep on building...Ed Quote Link to post Share on other sites
hubel458 6 Posted December 10, 2015 Author Report Share Posted December 10, 2015 Here is a fancy stocked 24ga FH built on a NEF, built by a guy in Canada. Its straight back, high comb stock, handles recoil great.Neat looking work... Ed About our 2.17" 585 BB case for lever guns, pistols, etc,. It is made from our 585 case cut back to 2.17" long. With loaded length of about 2.8" work in lever guns, etc. Work in 71s, later 1886s, Henry steel frames made for 45-70. One guy is putting one in single shot action set up with Contender style pistol grip for testing in long rifle barrel, to simulate pistol recoil..Be very brisk recoil in a case that holds 110 gr powder under a light Minie bullet. Maybe work in a Rossi Judge with heavy barrel. Or rolling block rifles and pistols...Gonna try one in 1887. Got first one in one of our guys Greener GP for testing.. AND LATER DO ONE IN A SAIGA In some ways big bore shotguns and rifles are sexy. By looking at the shape of the fire and smoke cloud.... Thanks for picture, to the great NitroExpress Forums site. Here is picture of another neat sporterizing deal for Enfields. On those without rear bridge pocket welded up, we just mill down and shape it so debth of the pocket matches bottom section of weaver rail and screw or epoxy it in. Shape to drive in hole tight. Can use as a rear scope ring mount or mount for peep sight like a compact UTG sight...Ed Quote Link to post Share on other sites
hubel458 6 Posted January 24, 2016 Author Report Share Posted January 24, 2016 A poster reading our threads said '' I'm slowly becoming a recoilapheliac''.. That is neat term , and very glad that folks are catching the big bore fever. Here is a simple, yet neat peep sight we can use on the rear sporterized bridges of Enfields, works on other rear bridges also.Including shotguns. I like peep sights the best for most shooting. They also come with flat bottoms also for bridges and receivers that are flat on top. Another picture of the 585 HE one of our guys put in the MPI stock.. Here is another pic of our guys 24ga FH in the NEF On straight sided cases like our 585 HE the die set has a mouth expander die to make it easy to insert bullets. The die flares the mouth, but I always felt that doing what is really a relative relatively sharp flare, and then the slight roll crimping the same area of the case into a groove on the bullet or slug, shortens case life. So I just use expander plug out of the die, by hand, using just the bottom of of the expander plug and just push it in a little, wobble it around a small amount, bullet goes in ok, case mouths last longer, good for dozens of loads, with moderate hunting and target loads.Only takes a few seconds and less work that has to be done in the press ...

The style of most break actions singles aren't the greatest, that we we used for 12ga FH, 10ga FH, other caliber barrels we mono-blocked in them like .585" bore for 585HE and 24ga FH.. One that is close that we have, is the Magtech. Well the guys have found one that is super strong lockup and looks real nice. And has the good quality look. It comes 12ga light shot barrel, soon be monoblocked to rifled 24ga FH, the little brother of the 585HE. We told company if they did them with NEF style, rifled, heavy slug barrel, for shotgun caliber only hunters, they couldn't make them fast enough. Here is picture of 585HE, In an Enfield that Bret and Darrel in Minn set up with great camo finish, with nice brake job..

Here is a helix driver seal we made by cutting base from helix driver wadcup, good for fullbore roundballs that are too big to go in cup. Best one to cut off is shortest `12ga one BPI has. Here is picture of a 585HE made on a Stiller bolt action for guy in Canada. It was made for the poster Spooksar on Africa Hunting and Accuratereloading, by Corlanes/Rocky Mountain rifles, in Dawson Creek BC Canada, with a Stiller action, Timney trigger. the stock is a blue/grey laminate. He imported the barrel, cases, dies, etc.. from us, through Prophet River in Lloydminster AB. That action similar to Lawton we had and neighbor got, that won the King Of The 2 Mile shoot at Whittington, with the 375 Lethal cartridge the neighbor made, from our 585 brass. Made it full length case,.. It is big one on the right. He made an 18 lb gun with McMillan target stock, a huge scope, tripod.. Nice thing is we don't need BMG action. Here is picture of a case a Trex owner made using our 585 brass, by putting a piece of 11/16 tubing ,cut a piece 2/10 of an inch long with a tube cutter chamfered the cut side a bit and tapped it on the case down to the belt with the brass pipe and fireformed it in the T Rex chamber.......Made a perfect fitting case. Cut our brass to 3" to fit shorter trex specs. He was out of brass and couldn't find more, so he invented his own. Our rim still big enough so the extractor on his gun worked ok.Ed.

Lethal Precision his own gunsmith shop, will make these target rifles for anyone into target shooting and long range hunting.. Remarkably, Mitchell nailed first- and second- shot hits at the 2477-yard target, a full 1.4 miles away. It is windy out there, makes shooting hard with a time limit. The prototype 400 grain Berger Bullets solid was superb, (G7 BC of 0.56 at 3000 fps). Here is 585 HE in an Enfield, in a Choate Heavy Varmint Stock. These are super strong.

hubel458 6 Posted January 7, 2017 Author Report Share Posted January 7, 2017 Our friend Brian from the far north went to Africa with his 24ga FH he did in a NEF break action and got 3 nice buffs with it. Good job. Our 585HE, 700HE and the great 12ga FH are now in the new COTW book published in Oct, now out for sale, We now have our target 375 HE cartridge, made by necking down our 585 HE. The others couldn't make enough 375s, so we started our own. It has different shoulder taper, length, neck length, improved over the others...Got a bunch guys doing it, most into the 2 mile shooting venues, We're making cases, testing, reamer prints at reamer guys, we are getting guys going. The 2 mile shoot last year really got the interest booming for 375 necked from our case, Here's how, size and seat 375 HE, one simple die, a 1" die, no huge dies needed A die we can make with resize reamer from reamer guy, a regular die body,then pass on to the next guy, one reamer can make whole bunch of dies for folks. I do primer work separate, not in the press. SO First with lock ring set, I size cases. When coming back out of dies with case, we notice the case still well centered, held straight, when it is down as far as the length of the 375 HE neck... IE the sides and shoulder corner still supported tight. So we put washer or another lock ring on, same thickness as neck length, below original lock ring, screw down tight tight in press, Dies had a 5/8 x 24 thread in top, had powder fill bushing and other stuff same thread, reamed out from bottom to set bullet height, with ram, case,and bullet up, After priming, loading in the powder charge, we carefully start(boat tail makes it easy) bullet in case by hand, slide up in die, into holder, raise ram to to top, bullet seated perfect. Die can have different thread in top as long as big enough to hold seating bushing of some kind , that can be made from many items. These target bullets held in by strong neck tension, no crimping needed, and notice bullet point will get no marks or dents, fast, easy, no 380-500 buck special dies. Bushing centering bullet on ogive is very accurate. OVER 900 375HE cases piled behind presses getting done. About 600 on another bench nearly ready. Small batches in shelves.And we will do more. All 375 info, prints, specs, pictures, load data, etc, is public domain, worldwide, for any target, hunting, etc, use..Ed Quote Link to post Share on other sites

In picture, 1st case is 416 HE, 2nd 416 HSM, 3rd 375 He, 4th 378 WEA. 416 HSM will get 400gr to 4100 plus without needing BMG action, 470 gr 3800 plus , it may be the ultimate target, singleshot 416.. Case will work in fat bolt actions, with heavy enough barrel to have good, milder, barrel harmonics and be under 50 lbs. A lot of the 2 mile type shoots are adopting 50lb limit. Here is picture of the 416 HSM fireformed once, next to bmg case we make it from and as we improve wildcatting process next few weeks some specs may make small changes, now from base to shoulder is 3.45", case 3.97" long. Ed.. Manson has 416 HE and 408 HE prints, as well as 375 HE He can also make you a resize die reamer from that info.

Second is model of what I'd have made on medium machine, if I could, the 416 HE Long. It has capacity of 230gr.. Third is our 416 HSM which we are working on making by wildcatting bmg cases, And if had run long cases, make longer 375 HE necking down 416 .. Bryan Litz just recently shot 3 shot group at 2 miles using Paul Phillips heavy barreled, target rifle built by Lethal Precision in 375 Lethal Mag(585HE necked down, very similiar to 375HE )...

hubel458 6 Posted February 12, 2018 Author Report Share Posted February 12, 2018 For big long cases our testing is showing that the 416 easier to get powders to work with, less problems .. Maybe building a target gun,don't have 375 barrel all ready, maybe go 416.... We got cases, 416 HE and 416 HSM, as well as 375... CEB and others will have bullets...CEB will be doing .416 in 450gr, 475gr, 500gr, 525gr and 550gr Got sent 5 thick sided sample cases, same OD base as 585/375.416 cases, same belt, just .180" longer, did a 416 HE, chambered extra barrel , cases stick over 50k. They have about .042" total taper, .021" per side, when I necked couple to 416. That is a lot of taper , twice the taper of my 416HE...hanging up at 50k.. I could maybe go to 65k with these if we made taper with ..012" - .016" more taper to each side, but that is no way to build target cases. I'd have to crunch down case shoulder diameter. And would look like 30-30. And crazy part is, the case has enough brass material to thin up sides and stretch them way out to 4 or more inches,, They weigh 150 gr more than our 585/375/416,, but with real thick sides they actually hold less than our 416 HE with thin sides, that is .180" shorter...Our case does 65k ok without sticking.. And we can make super long 4" cases work if we had means to get them built, as we have 15 powders slower than HBMG.Here is pic of thin and thick sided cases, sectioned for comparison.Ed..

hubel458 6 Posted March 5, 2018 Author Report Share Posted March 5, 2018 Here is a drawing depicting the layout of thick and thin sided cases, like my 585/375/416 HE thin sided ones and the thick one in picture. And my 585 case is not perfect, as where it transitions from the heavier corner to the side it isn't gradual, so case separates there shortening case life. There are others made that way including brand X. The dotted line is what it should be............ Others have sent cases to section and look at, that are built thick sided and they stick also for the folks, If a longer case with about 5 sq in of side surface sticks and don't spring back, the coefficient of friction is about .01 then the pull needed to move it is 2500-3500 lbs..That is for big cases with normal amount of slant to the sides. Here is picture of six nyati and gibbs size cases sectioned.. the5th one is present 585 HE and 6th is thick sided version. 1st 600 OK which essentially nyati basic case left straight, belt added In the picture the nyati gma is one we built most of our first 585s on. Before we had factory run. Reworking made it in size that is my 585 HE, but that brass had the sides of perfect thickness, not too thick, but thin without sharp transition my new factory 585s had, they last forever as 585s...... Fourth one is an older nyati case I used to make about 10 of my 585s from,had thin sides, heavy corner and sharp transition from the corner, tested 20 years ago, and they would separate after 4-6 hot loads as 585s, my factory 585 with right powders, as a 585 will get 10 hot loads, and necked down to 416/375 4- 6 hot loads, right powders used, Moderate 577 equivalent, factory 585 at least 20 loads..Ed.

hubel458 6 Posted March 21, 2018 Author Report Share Posted March 21, 2018 Guy sent thick sided 375 case, next size base diameter up from Nyati.He said, 'Yes I ran them in a ___________ rifle built by ____, the best I could get was 44000 psi, any more and they were stuck'' Big bore guys. other forums over the years related that trex/african case in 585 size, thick sided cases, stuck when they loaded them over 45k psi. Another just sent us, thick sided 375, long case, same base OD as our 585 HE, 416 HE, 375 HE, and Mitch's 375 Lethal, and the thick ones stuck over 45k psi. Now you can fill those cases up, with ultra slow enough powder so they won't stick, but powder is too slow for max speed. Might get a little more speed, with thick sides case, but case got to be 4- 4.5 inches long.. .

Then sides would be perfect.., .
