Warmish loads with 255 KB, mag primers, N350?

Post by Tactical Lever »

Hi guys. Looking for a warmish load for Bisley Blackhawk. The max that I've found for regular Colt loads is about 11.2 gr. of N350 with I believe regular large pistol loads with a 255 gr. cast, or 250 J bullet at about 1050.

I figure that the magnum primers will give me a bit more velocity with a bit higher pressure and a complete burn. And I was going to go a bit heavier charge at about 13.2 grains. Seems like it should be well within Ruger large frame capability when I compare case volumes and similar loads for .44 mag and .45 Ruger loads. But will it be a good combo for the 255 gr. Keith bullet? Should it be a decent shooter?

Looking for about 1200 fps out of a 7.5" revolver.

Thanks guys.
