[QUOTE=".280Rem, post: 199239, member: 11140"] Since all .280 data is at or under 60Kpsi, and it's safe to load it to .270 pressures of 65K psi, I find that hard to believe unless you have a very tight tolerance custom bbl. I have seen a custom .280 that wouldn't take max loads. I consistently run 2-6 grains over book max powder charges in the .280Rem, and with my velocity, Quickload still says I'm hovering around 62K-63K psi. I'm running 139s/140s 3080-3150fps, and 150s/154s 2980-3015fps in a 24" Rem 700. What are your velocities? Afterall, that's what counts when it comes to pressure, not the on paper max powder charge. To answer the original question. R-22 is the cat's meow for me and most in the 7mm. 66grs and a 160 Accubond run 3080 in my 25.6" bbl, and get under 3/4". [/QUOTE]
