Loaded up some Cast Performance 410 grain WFNGC bullets in Starline brass, using 21, 21.5, and 22 grains of H-110. The upper left group is 5 shots with the 21 grain load. Average velocity was 1105 fps. The bottom right is the load with 22 grains. Average was 1158 fps, and extraction was a little sticky. Top right is with same bullet in Buffalo Bore factory ammo that I used for a comparison. Bottom left is factory 325 grain Hornady's. The Hornady brass worked in my Lee #5 shell holder for resizing, but would not go into my Lee #5 shell holder for my priming tool. Settled on the 21 grain load for bear this fall. I used CCI large pistol magnum primers in all loads.
This is from my SRH with a 43/4" barrel. She's a keeper
