Interesting, Looks a lot like the cartridge that I’m currently playing with, Wilson’s 300Hamr. A 223/556 case shortened a bit and enlarged to .308. Haven’t shot for groups as I’m still trying to get my mini14 that was rebarreled to 300blkout and then recently rechambered to 300Hamr T20 build running. I needed more room in the case for more powder to get more gas to run the gun. Good thing is I was able to get a 300Hamr case cut off tool for my HF saw and lee dies which made building cases easier. It’s finally coming together I think. Pix is a Ham’r and a blkout.
