Current good load is 44.0 grains of BLC2 under a 165 gr. Speer BTSP popped with a Federal LR primer in Sig brass. 5 shots in .5 twice. more testing to come but this will do it.
I got very similar results using the same brass and primers but with 44.5 gr of RL-15. My best results were at .130” off the lands, as mag restrictions had me starting at .110” off the lands.
