I have a few .410s single shots and O/U that I shoot brass cases in.
I would like to shoot some round balls in them.
The end of the bore at Muzzle measures about .487-.488 with a set of dial calipers, don't have a inside mic that small.
DO you thinkin I could shoot single ball in the brass cases thrown from a Lyman .490 mold not patched , made of soft lead?
I don't want to harm the barrel , some of the shotguns I wish to use are a pair of Old Savage 22/410s.
Thoughts?
