    Interesting; I’ve never heard of a shotgun or puntgun referred to as “bore” since pounder/gauge were the standard for centuries. I’d guess this one was just made at a conveninent diameter but still expect it was a 1 pounder for it’s square load.

    Anyone have some good sources (books) to read up on puntguns?
