I just bought a new (old) gun, a Remington rolling block in .43 Spanish. The bore is in nice condition for it's age. I haven't got set up to load for it yet; I need to get some dies and molds, and most of all brass. I had one modern round that I picked up somewhere, that I fired today. On looking at the empty, I noticed a couple "bubbles" on the neck, and realized that at some point in the past the neck of the chamber has been gouged.
I assume that there's really not much that can be done, other than just shoot it. Anyone else deal with something like this?
