For mild to moderate surface rust, Marvel Mystery Oil and a bronze brush that is slightly oversize will work well, followed by more MMO and cotton or linen patches, It will be a bit of work but will clear up the bore nicely, keep repeating the process until your patches come out with no brown on them. If there are pits in the bore this will still work, but the pitting will remain, making loading difficult at best and effecting accuracy. You can have the barrel "freshed out" or re-bored by a smith or replace it all together if it is too far gone.
To check the bore of a .50 caliber black powder rifle, first ensure the rifle is unloaded and safe to handle. Use a bore light or flashlight to visually inspect the interior of the barrel for any obstructions, rust, or fouling. You can also run a clean, dry patch or a bore snake through the barrel to feel for any irregularities. Finally, measure the bore diameter using a caliper or a specialized bore gauge to confirm it matches the .50 caliber specification.
A very mild acidic cleaner <><><> For light rust, soak in penetrating oil (I like KROIL, but PB Blaster is good also) overnight. Rub with clean coarse cloth, such as burlap. Deeper rust may require stronger methods. Try a copper pot scrubber, such as a Chore Boy pad, toether with the oil. INSIDE the barrel, use a good bore cleaner, and a bronze bore brush.
