I hand load for a Rossi 92, 16 inch barrel .44 magnum. My standard load is a lead 200 grain round nosed flat point at about 1000 feet per second. This is with Bullseye. large pistol primers and magnum cases. They shoot and cycle fine, but the cases are very dirty after firing. I do tumble my cases before reloading. I have also noticed that unfired rounds, if cleared from the magazine are often dirty, indicating a build up of powder residue in the magazine. Is this just a feature of Bullseye powder? My reloads cycle well, I seat the the primers below the level of the primer pocket and the bullets are secure with no sign off movement or being set back when cycled or moved through the magazine. Would increasing the crimp on the case reduce the fouling? I occasionally shoot magnum, both factory and home rolled and haven't noticed it with these.
Any suggestions really appreciated.
