I shoot a Browning BPC Highwall in 45-70. I am fairly new to this black powder cartridge shooting. Recently at a match one of the other shooters told me I should be using Ballistol on my bore after final cleaning. He claims it protects the bore of a BP rifle better than many of the normal gun oils that contain petrochemicals. Something about black powder barrels developing a seasoning, and ballistol protects this seasoning. I do use ballistol as a general lubricant and in the bores and cylinders of my revolvers, but they are smokeless powder, not black.
Should I be using ballistol on the bore of my 45-70?? Pros vs Cons??
