My brother-in-law and I bought TC unmentionables as our first trip into the muzzleloading adventure. We used Pyrodex and Triple 7. Then another friend got me interested in a TC caplock Hawken and real black powder. So, I put the unmentionable away and started using the Hawken. One day while shooting I noticed my brother-in-law could not get his bullet down the bore after one shot. He complained that it was a pain that he had to swab it out. He was using bullets and two 50 grain Pyrodex pellets. I said clean your gun and try some of my black powder. So, he cleaned it up really good and we poured 100 grains of 2fg Goex in the unmentionable along with the same bullets he had been using. He shot it and then tried to reload. What a shock as the next load went down without swabbing. I think he took 5 shots and did not need to swab. He is a convert to real black powder however when I switched to flintlocks, I could not convert him. He shoots his unmentionable and I shoot my flintlock and we both use the same powder.
