Yep, nice gun. If you’re new to BP pistols make sure you follow guidance locally of others who can show you in person. Am guessing you’re a member of a BP club. Start with loadings from the Pietta manual (should be online if you don’t have a hard copy), or see what the previous owner had down as a good load. BP would be better than Pyrodex in the long term (cost, authenticity) and like most do, lube over your balls once loaded
