I'm not meaning to call you out on those numbers, it's just that I'm loading a 69 grain TMK over 25.9 g of Varget and getting 3140 fps out of a 26 inch 8 twist, which is about 100 fps faster than book. Still, nowhere near the performance you're getting with those 80's. (Hogdon says 2860 fps with 25 gr.) What's your secret? Grain for grain, you're kicking butt!
OP says he's set up his barrel for the heavies, so presuming he's got a throat cut for the 80's or 90's, and can seat long, he should be looking to stuff more powder in the case than book values and get more velocity without excessive pressures. Do I have the right, or have I learned nothing?
Seriously, I'd/we really appreciate your input. Thanks in advance for any help.
