I bought a 50 caliber Renegade. The bore is pitted enough that when I run a clean patch down the bore, I can feel the roughness of the patch rubbing the bore all the way from end to end, and it is somewhat hard to pull the patch and rod out. With a flashlight, I can see where pieces of the patch have torn off. It looks like snow! A bore butter patch is still rough feeling. There is rifling, but I wonder how well a patched ball, a sabot, or a maxi or Great Plains type bullets will do in the bore. Patches all come out over and over with brown on them no matter if they are clean or treated with bore butter. I guess what I am asking is whether the barrel is done, or can it be bored out to 54 or 58 caliber or what other options I have.
