All this talk of PA Hunters I decided to shoot it today. My load was simple, 90 grains of Graf's 2f black powder and a moose milk. pillow tick patch with a cast .490 roundball. This was at 30 yards. The real shocker of the day was when I tried an off hand, and I mean just pulled up and shot. A little off but it needs more work.
The two different groups were because I shot the first, to the left, and then was sitting at a strange angle on the bench because of the melting snow. So I shoveled my feet flat to the ground and shot the next group.
I did not swab the barrel. I did notice some fouling building up but did not care. I had a couple more rifles to shoot. It was 43 degrees out and not even windy. Nice to sit out there without a jacket on.
