Those of you familiar with the model 92 have you run black powder through them? How terrible are they to clean afterwards? I normally run a 66 or 73 in 45 colt with bp loads. but I found a Rossi 92 in 44-40 at what I feel like is a hard to pass price. I pretty much only shoot true BP and I'd certainly only run BP in a 44-40. How could I not? Lol    Thanks   T.F. Jack
