I had one that was gifted to a lady, I set it up with 445 ball, 60grns of Pyrodex P and an .11 denim spit patch, thing was driving tacks.
Someone else told her that load won't work and loaded it with 440 ball, 45grns of Pyrodex P and a .15 pre-lubed Ox-yoke patch, the thing is driving tacks, :idunno:
