After carrying around long barreled heavy rifles for years I wanted something that hit hard and was more packable for mountain hunts. I've always been a big fan of the versatility of .30 cals. After years of shooting game with cartridges from .17cal-.338 I favor bigger calibers even for deer sized game. Just less margin for error at the cost of more recoil. With this build I wanted to try for a do it all rifle, medium weight with the larger cartridge, and something that gets preference every time I go hunting with the exception of varmints. All I've done so far is a pressure test with 215 bergers, ADG brass from Rich, N570, and shot some factory PRC ammo. I will be posting results over time as I test multiple powders and bullet combinations. Imr 8133, H1000, Ramshot LRT, 230 Berger, 220 Berger, and something from the Hammer line. I will post rifle weight when I get a chance to put it on the scale. As always a big shout out to Rich for his help and all his efforts to create innovative cartridges.

These are case web measurements just above the extractor cut measured after the case was sized on each firing.
virgin unfired .529"
83gr 1X .5315"
84gr 2X .532" 2881fps
85gr 3X .532" 2917
86gr 4X .532" 2946
87gr 5X .532" 2983
88gr 6X .5325" 2986
Velocity is right where I expected it with the proof. I hope to find my load around 85-86gr with the 215 bergers.
Velocity Data was measured with a Magneto Speed. I recorded one shot from factory 300PRC ammo with the 212gr ELD-X at 2626fps.
I will continue to update this thread as I test and gather data. Rifle has 21 shots through it as of now.
