I love to shoot mine, its cheap, fun and accurate. I have a custom made .32 pistol to go with it that has a 12 inch barrel and is a super shooter also. Of my 4 BP pistols and 4 BP rifles I have, it would be the last to go if I had to get rid of them. I bought mine used along with a maxi-ball bullet mold for it around 20 years ago. Never used the mold it is still new. 20 gr powder, 310 ball, .15 patch and its a shooter. I swab it between shots, it tends to foul easy. The only thing I never liked was the single trigger. It was the hardest pulling trigger I ever had. I worked on it several times, but finally decided to leave it alone, seems to me the spring is just to stout. Finally after years I got on eBay a few months ago and bought a like new stock with double set triggers on it. I dropped my barrel on it, and it is so much better to shoot its like day and night. They hold their value, I gave 295.00 for my new stock with double trigger and lock on it. I shoot it more than any other BP gun I have. T/C’s maximum load for the .32 is 50 grains FFFg black powder. I don’t have loading info for the .32, but here is the info for the .36 Cal.
