Had a guy reload for my BLR 81 in 358 years ago. Could only get 2.5 inch groups with any 200 gr factory loading, including the newer Hornady. It shoots half inch all day long at 80 yds with this load. 250 gr Hornady RN bullet. CCI 200 primer. 41.1 grains of IMR 4320. And drops deer dead. It did take awhile to figure this out. Don't know what FPS it moves at.
