I have 2 Renegades and several other 54 caliber rifles it was my preferred hunting caliber from 1977 to 1998when I started using inlines a good part of the time.
The load and bullet often depends on the twist I have had a 1in 38 which shot 200,230 and 140 grain bullets in a sabot quite [100 grains RS] well but most of mine are 1-48, 1-66Twist the 1-48 twist is quite versatile it handles a sabot with a jacketed bullet of 180 or 200 grain [110 grains RS] or a 400 grain conical or a PRB [110 grains RS].The slower twist I use PRB and a heavier powder load. Some people do not realize it but a 54 loaded right with the right size ball and patch and 120 or 130 grains of Pyrodex is quite capable at as far as 175 yards any one that doubts that should go to friendship and watch the Hawken match. I have taken both deer and bear at 180 +yards with them with open iron sights. The sights were hand made by me for the Hawken match and had two "0" one at 100yds and one at 177 yds. Some times I wonder why I started using the inlines so much I actually believe that a properly placed 54 caliber PRB drops deer on the spot more often than the saboted bullets I am using, which tells me I should start using premium bullets.
