[QUOTE="highdrum, post: 1957540, member: 13732"] Rich.......how does a case with 3 grains less powder capacity run 100 fps faster in the same barrel length? Or even shorter in some instances. It's more pressure in the chamber, that's the only way possible, physics. I've got a 25sst, and a 7 Sherman max, and a 6.5 max soon to be done. I have yet to see speeds that others/yourself have achieved. I'm running your brass, 26" barrels, I anneal with an amp, auto trickler, best bullets and powders money can buy. What am I doing wrong? Am I getting junk barrels every time around? My 25 sst has 110 rounds on it now, and the other day I had swipe with almost everything I test from 3040fps-3300fps, 131 ace, N565, N570, Rl26, RL33. Action is a Terminus Apolo, all top the line stuff. Both rifles have proof barrels, and these will be the last that I buy. I just don't think I'd get bad ones back to back. Their shop is 5 miles down the road maybe I'll have em gauged. [/QUOTE]
