RE: renegade loads
You're going to have to see what shoots best out of your rifle. I'd start with 70 gr of FFFg with both a patched round ball (PRB) and conical like the Maxihunter or Maxiball and work up. My 54 cal Renegade shoots a PRB with 80 gr of FFg excellent. My 50 cal Hawken shoots the 275 gr Maxihunter over 100 gr of FFFg very good. Both of these barrels have a 1:48 twist.
