That's great - .715's - I take it there were WW alloy. The .710's at about 538gr. in pure should also be close.

Patched, well, how about that. Sure worked well for my buddies in their pump 12 bore duck guns - for shooting moose from the duck blind - that was in the 80's. They also worked well in my 16 bore. Smoke - what primer did you use with the 4759?
