  1. More about our 416 HSM from BMG brass, and our 416 HE & 460 HE from our 585 HE cases Got reamers for 375 HE, 416 HE and 416 HSM,.... 460 HE & 460 HSM are all spec'd, got HE reamer, soon have HSM reamer...Our HSMs have a Wea type radius on the shoulder.. Guys getting ready to do 460 HE and 460 HSM. The fellow that set up our 416 HE in an ELR rifle and tested it at 1200 & 1800 yds , They got some game out west over 1400 yds.. .Here is the gun they set up. Using a K&P 34" barrel on a BAT action.....Ed http://www.gunownerstv.com/jacobgun.jpg
  2. Got guys doing various 416 HEs.. One just built a 416 HE, just been testing it a few days.. And using 168gr of HBMG 475 gr CEB, tested it, in good conditions, 2 shots at 1800 yards and was within a 1/4 of minute accuracy...A few shots at shorter ranges had same accuracy. Ed..
  3. 20mm Vulcan is a big case that works ok, without having the sides made too thick...They have thinner sides than smaller cases guys are getting that have the sides made too thick and won't extract easy or work with high pressures. Here Barnard P Cheytac bolt that would do for our 416 HSM..Ed......
  4. Wonder if a PTRD with 5 ft long barrel is stable enough for ELR , rebarrel to 416 and use our 416 HSM, 500 gr bullet .... .Here is up north guy using 585 HE in a PTRD with inserts, Light load.....Inserts are in the shape of the 14.5mm case.... https://www.youtube.com/watch?v=jyabm-cbwgc&feature=youtu.be HERE ia video, 585 Hubel Express and water jugs - slow motion 750 gr with 155gr RE17, just a moderate load.....Ed https://www.youtube.com/watch?v=uXAo1mJqw8Y
  5. ..... It is possible rig up holders for many types setups., About shellholder supply for big cases, RCBS and others make slip in holders for shotgun cases that can work or reworked for big rimmed rifle cases... Here are various sizes....... 16ga-- .810" rim,........ 20ga-- .760" rim,.... 24ga-- .725" rim,....... 28ga .680" rim.... Ch4d and Buffalo Arms also have these larger shellholders... We fireform the 416 HSM with 65 gr of medium speed surplus powder, with rest of case filled with farina and grits mix, with a play dough plug in the neck. It is loud, so we shoot it into big container through a barrel size size hole, so the sound is muffled, so it doesn't deafen us.. It is great getting more companies making 416 caliber bullets, long target and bore rider bullets. Ed.. ....
  6. Bob Snapp, 90, the great Gun Craftsman, of Clare, Michigan, passed away Jan 28th.... He was an esteemed member of the American Custom Gunmakers Guild, Being its president in 1992..He liked working with Martini Cadet singleshot rifles .Worked with guys testing armor long time ago. Maybe the 1st to do 20mm necked down to 50cal We lost a great friend,,,Ed

  8. None of HSM cases are too thin, Yes we use BMG primers..in the HSM. Here is picture of our 416HSM cases with screw in shellholders, for Ammomaster, etc, and slip in shellholders for regular presses Also have some for big LEE Classic and Smart Reloader presses.. A 378 WEA MAG in picture for comparison... Second is stacks of 416 HSM, about a third fireformed and the rest to be fireformed... So far total about 1700, Ed
  9. In 416 HSM got a 415 gr long target bullet 3800, with plain barrel, no brake, on intermediate action, Now my 416 HE gets same 415gr bullet to 3300.Ed
  10. Here is video of early water barrel test of the 12ga From Hell, from years ago. https://www.youtube.com/watch?v=c48zTpsgbuk Here is picture from that video.. Here is the intermediate size action for 416 HSM with test barrel, .Ed
  11. Here is picture of the bolt from the experimental action, with our 416 HSM case in it. Note the amount of the base size of locking lugs, the amount of area on the bolt.. Here is link to guy doing special 585 HE in the EU, Good pictures............www.585he.cz We tested intermediate action with a 700HE barrel we had here. Just temporary to test strength. 1000 gr over 3100.. Action worked fine.. Ed.
  12. Experimental intermediate size action with the Montana PH, for comparison. It is an experimental action for our 416 HSM, to do our speed testing with and get a better action than Cheytac size actions, for bigger case ELR use, without going all way up to more expensive, huge actions. It is big long round style action that can take our 416 HSM, almost 1.6" diameter and .800" bolt, with locking lugs nearly as big as most BMG actions.... ED
  13. About 416 cal bullets............ The heaviest 550 gr for Extreme ELR probably be best 8 to 1 twist , in 416 caliber bullet, and 520 gr 9.5 to 1, and 470gr 10 to one, Some barrels I picked up are 10 to 1....... Now a novel idea is to lighten rear of bullet with small shallow hole drilled in base, might do better long range.which would allow 10 to one barrel stabilize the heavier 550 gr bullets for ELR. Making bullet nose heavier makes it more stable in flight, needing less spin, like our hollow base 585 cal minie bullets only need 48 to 1 twist, or less while out regular 585 bullets need about 24 to 1 to stabilise them.............. The winner of the King Of 2 Mile shoot last week was using 416 Barrett with a 1 to 10 twist, with a 500 gr CEB Lazer bullet, ...Robert Brantley, with Manners Stocks.... Paul Philips was third with a 416... GOOD NEWS-- There is now an importer and seller of our 585 HE brass getting set up here, in US, hopefully will be in stock, few weeks........ http://bertrambrass.com .. .. Caleb Hallet.. Have got another intermediate size action besides the Montana PH our guys working on, to do speed testingwith. It is big long REM style action that can take our 416 HSM, ED
  14. Here is sectioned 585 HE case in the middle, we first made from another case, years ago before we had factory run of brass and it had perfect thickness on the sides and inside corrner. We could fire them many times without sides thinning.. First case is factory run of our 585 HE, 3rd is case that is too thick of sides and sticks at high pressures.. Here is pic of our factory run cases necked down to 375 and fired 4 times at high pressure on the right, with unfired case on the left. Our case is not perfect but does work...Ed
  15. Here is picture of thick 375 case sent to me, with thick sided trex case, and our HE case, The thick 375 case is .050" bigger OD base, but inside is no bigger than HE cases.. These thick sided 375s stuck for the guy using them, when loaded over 44,000 psi.... Got guys asking and doing it, to do 416 HSM case for BMG actions, so leaving rim same, as the original bmg rim, so will neck them, fire form to the longer shoulder, like the others. Base a little bigger, Shoulder same diameter, same 30 degree slant, neck will be same.. Inside of case still has close to same shape, volumne within 3 % as ones we slimmed down more. Some want to use bmg actions and can't wait for intermediate actions, or already have bmg action. And they are really getting interested in the complete line of 416 CEB bullets now being done clear up to 550 gr... So there will be 3 versions, one for actions .750" bolt, one for .800-.850" bolt, And one for bigger bmg bolts. The ones for BMG called 416 HSM2 .. Here is 416 HSM guy working in a Montana PH, in a heavy thumbhole target stock. Ed
