Worked up the ladder today with 140gr SST and RL22. Pretty disappointing. I got tight groups with two of the charges, but couldn't get much better than 2400fps, even over book max. Perhaps because my rifle has a huge throat and I have the projectile's seated out to the limit (46.5gr is meant to be a compressed load, nowhere near). Have got a bottle of 760, starting at the .260 max load and working up.
