Ron I'm going to be trying the 11mm paper patched and the 340-I bullet for starters. I also have a 500 gr mold and 405 gr mold that I shoot out of my .45-70s and I can cast some out of pure lead and size down. I didn't have too much luck in the past downsizing .458" to .451"
I recently picked up an adjustable .45 cal sizing die so I can fine tune to the diameter I need.
