[QUOTE="Brent, post: 5721, member: 99"] Sam, We tried H1000 at 65gr with a 140 SMK, the thing was smokin along at 3277 fps average but, pressure averaged 71,800 though. Bolt was stiff every single shot and dad said primers seated pretty loosely on the next loading too. He backed down to 63gr and we have yet to check pressure on that one yet. It wasn't stiff extracting though. The A-Max "seems" to come in a little lower on pressure from what I've seen with it so far, maybe by about 3k psi or so for a given bullet weight. Bumping the load up a grain or two for the same velocity or a bit more is what I've had to do. We're getting between 3175 and 3250 fps at around 65k psi with most loads so far. You may want to keep track of the throat errosion pretty close, he's got about .025" errosion in about 300 rounds so far. Enough that he can't reach the lands unless he only want's the bullet a little over half way down the neck now. I see a set back coming soon. RL25 seems to be about the best so far, no matter what bullet too. [img]images/icons/smile.gif[/img] [/QUOTE]
