My load is 37 gr RL17 with a 75 gr SSII .055" off the lands out of a24" 3 groove 1 in 7 twist Pac-Nor and gets ~3215 fps with an average extreme spread of 15 and standard deviation of 7 or 8
Warm load so work up to it. 33.3gr R15 behind the 75gr Amax. Routinely groups in the .3s to .4s and clocks a little over 3200 from my 24" 8" twist Criterion. Deadly on Whitetails and coyotes.
