Anybody load for 8mm hugo mauser? I found Hornady 8mm .323 did bullets SP and I measured the commie rounds I bought with gun and they measure .320-.321. I thought they were either .318 or .323???
53 grains Varget, COL 3.000", CCI200 primer, S&B brass, 175 grain bullet, gave me 2750 FPS at a measured 53.8 KPSI.
Quickload show 53.0gr Varget with a Sierra 175gr SP at 3.000 generating 65.1psi.
Military rifles vary considerably in internal dimensions, and your results in your rifle will surely be different.
If you measured the bullet diameter at the top of the case neck it is likely not the maximum - pull one & check it below the ogive. I haven't seen one less than .3225" but it's a jungle out there...I measured the commie rounds I bought with gun and they measure .320-.321
