I have White Label Lubes BAC and Carranuba Red. I used the BAC this time. My goal was 20-21 bhn with quenching, and I landed right about there. Sized .4015. Only fired a dozen through a chronograph into a snow berm to verify function and that my load from the Beartooth bullet is still viable. No keyholing at 15 yards, and velocities were spot on. I did have to shorten my oal from 1.255 to 1.227 to get the driving band inside the case.
12.5gr of AA#9 got me 1150fps, and nice straight line variation up to my original load of 13.5gr and 1250fps, matching the performance of several commercial hot loads. Again, this load is safe in my gun, not necessarily yours!
Minimal leading, slightly more than the gas checked Beartooth version, but certainly acceptable.
