I get 2900fps =/- out of my 22" Proof barrel running a 175gr ABLR with 69.3gr N565 out of fired Peterson brass & a Rem 9 1/2 primer. BTO of 2.6650". More importantly, it's an accurate load. I loaded up to 71.3, but saw no accuracy improvement.68.0 grains early on gave me right around 2940 and I just checked my notes, and I got right at 2960 with the same load at around 80 rounds. I'm now at 140 rounds but have not put it over my chrono to see how much velocity I have picked up. I hit pressure signs at 70.5 and accuracy was going south, so I took it back down to the 68.0 grain load that shot really well and that's where I think I'll stay. Obviously work up as every rifle is different.
