Finally got out to the range yesterday. Fired a few rounds. My biggest problem now is the fouling caused by using real black powder. After the third shot, if I don't swab the barrel, it takes a feat of strength to get the patched ball down the barrel. I am shooting 75 gr. of FFFG Schuetzen black powder, .490 round ball (Hornady), and a .010 pre lubed patch, winchester magnum percussion cap. Is this too much powder, not enough, what? The first round slides in like it's on greased rails. The second shot, requires a bit of effort. The third round requires some force. After that, forgetaboutit.
The rifle is a Pedersoli Traditional Hawken Target Rifle, .50 caliber. When I first started shooting it, all that was available was pyrodex. I have tried RS, P, and Select. I didn't have much problem with fouling. After finding a couple pounds of Schuetzen FFFG, that's all I have been using. I like the accuracy I get with Schuetzen but the fouling makes it a S.O.B. to shoot without "swabbing" way too often at the range while shooting and takes forever to remove the fouling from the barrel when cleaning it. I clean the rifle after every trip to the range and upon observation, there is no rust in the barrel. I am kind of at a loss. I could try a thinner patch maybe but I don't want the ball bouncing down the barrel. Thanks in advance for any help.
