The 32 cal crockett is a great gun . I bought one 2 years ago . I use 30 gr 3f,.310 ball and a .018 patch. It is accurate for me to 40 yards. I haven't tried much beyond that. I intended it to be the first blackpowder gun for my kids to learn on.It was so much fun that I shoot it more than they do. I never really experimented a whole lot with loads. I used Shockeys gold and different have a fouling problem. I figure for the distance I was shooting the velocity variation with APP wouldn't matter a whole lot. I used t7 3f also. That definitely is a swab every shot powder. I might have to dig it out and experiment some more now that you have me thinking about it.
