I used some of my 3/4" lubed wads and they worked well. I'm planning on making some 5/8" which will work once they're lubed. The lube makes them swell a little.
I picked up a used Pedersoli 1805 Harper's Ferry pistol today. I used 30 grains of Goex 2F and KIK 3F in the pan. It shot perfectly the first time, but I couldn't get it to spark at all after that. I'm going to clean it and go from there.
