Join the Muzzleloadingforum; lot's of good info there. I inherited my dad's .54 renegade w/ out a clue how to use it and that board helped alot.
Mine came w/ a box of round balls & T/C pre-cut patches. My Bro in law told me that he and dad were shooting 80 grn FFg and it works well. I used that load, after a season to sight it back in w/ the T/C fiber optic sights I added.
WARNING! the cloud of sulfur smoke is immediately addicting; enjoy. Shoot it often and clean it immediately and you will have years of fun.
