I've been BP shooting for about 2 years. Use a Pedersoli Kentucky Flintlock .50 cal., Goex FFg, Ox-Lube pre-lubed patches, Buffalo Balls round balls. Had no problem getting 3 shots per barrel cleaning, then a couple of patches and back in business. Missed about a year of shooting due to a move. Now, after 1 shot (same load) I have to clean the barrel. I mean it takes 4-5 patches just to get to the breech (3"-6" at a time). If I ram a patch down it gets stuck & I'm tearing the gun down and using vise grips to get the rod out. The patches seem to be waxy and VERY dirty. What gives? Powder absorbed moisture and leaves more residue? Not cleaning the barrel well enough in-between shoots? I'm at a loss. The powder is stored in it's original can with desicant gel stored in the same box. This has SERIOUSLY taken the fun out of my flint. Hope some of you can help with some ideas. Thanks.
