Redhat,
Yeah, I have a Renegade in 54. I really like the ff Swiss but it's to expensive to shoot all the time so I shoot the ff Goex. I've never shot the black powder subsitutes, I started with the black and have stayed with it. I'm a paper puncher and for me I find 70 grains is a comfortable load and I can shoot it all day long. I had a 26" barrel and sold it and bought a 30" TC 1 in 66 coustom barrel. It is a bit more accurate but I think the sights I put on play more of a part than the longer barrel. Was it worth the $170 yeah I guess so. [to me any money spent on muzzleloading is worth it]
Like I said earlier "try the prb you won't want to go back",,,,,,,,,,Jim
