[QUOTE="MrButterpants, post: 189801, member: 10550"] Ron, I'm shooting 69gr Nosler Custom Competition HPBT's ( a very similar bullet, BC .305) out of a RRA 18" varmint A4 using: Accurate Arms 2520 - 25.0gr LC brass WSR primers OAL~ 2.240" but my base to ogive is 1.863" AV vel = 2800fps (@ 40 deg F, 24.48 station pressure) No pressure signs. It's grouping around 0.5 MOA @ 100 yds but I don't shoot off a decent rest, just a picnic table and a few sandbags....might be better. When I developed it, initially I set out to duplicate HSM (The Hunting Shack's) 69gr HPBT match load, which is getting stupid expensive. My SD is 10 lower and vel is 150 fps faster not to mention the price is less than 1/2 and groups the same. I've run the load up to 26.0 gr (av 2950fps) but noticed a degrade in velocity and some very slight pressure signs on the cases (primers were fine, but the extractor was diggin into the rim base a little bit), so you've got room to play and don't need to worry about pressure when it gets hot out. Actually Varget shoot better groups in that RRA of mine but the velocity vs powder is better in 2520, least for me. Good luck [/QUOTE]
