So I'm trying to get into black powder cartridges so I bought a CVA Scout in 45-70.
My impression after reading stuff on the net is that most modern guns like .457 boolits and the older ones like bigger boolits like .460.
I tried slugging the bore and I was surprised that the groves measured out to .460. I'm not sure if this is normal or not but the largest I can size it the boolit to and neck size to is .460. Am I on the right track?
