Everyone is different it seems.
I'm no expert by any means, but I've "experimented" quite a bit, and here's what is working for me now.
Pedersoli Brown Bess (2nd land)
This has a .752 bore (miced) w/ 42" barrel.
Present load is 110 gr, 2Fg with a .715 RB (Lyman mold), .021 compressed denum patch (medium weight denum). I cut these into 1 3/4 squares, and stack them in a can with generouse amounts of Bore Butter in the center of each patch while stacking. Then with the top on the can I'll set it in a pan of simmering water on the stove for 1/2 hr. or so. These patches are well greased all the way through when done. I can "fetch" my used patch and reuse (do it regularly now and can get 4 shots per patch - 5th one gets frayed).
With the bore "buttered" at the first shot, I've shot 56 balls in a row (I got tired!!)without wiping or cleaning. Loading throughout is moderate force. At the end of the shooting it cleaned like I only fired 1-2 rounds.
3Fg gave me a heavy to extreemly hard fouling (can't figure out why though). The .018 Ticking kept burning through. The heavy jean mat'l was too hard to load and I think I was deforming the ball because they were constistantly all over the place.
110 grs, while "authorative", is not an unrully load. Gives fair trajectory and thus far is a good accurate hunting load.
The cheapest source I found for .715 & .735 cast balls is Dixie Gun Works at about $28.00/c plus S&H. Sure justifies casting your own in a hurry!
So far, this is what is working best for me. Hope it helps some. :m2c:
