  2. Here is print with chamber reamer specs for the 416 HSM chamber..There are 3 base sizes we have, depending on actions used. Got reamers for all 3.. Got cases for all of them.. Our cases are public domain, so that is why I post info and specs. Manson makes reamers I use,,, Ed.
  3. More about he guys that did the accurate 416 HE, they did a 416 HE that has an 8" longer 42 inch K&P barrel.. Used longer barrel and the same load with 475 gr bullet, as used in the first gun and and gained about 200 fps with good accuracy,. 3065 fps. Tested 2 groups of 3 and less than 1/2 min moa. And loads they used are not the highest speed loads the cartridge is capable of....Here is picture.......Ed....

  5. 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
  6. 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..
  7. 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......
  8. 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
  9. ..... 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.. ....
