I know I have see 32 and 36s, but what I was wondering about was something like a 25, or 22 caliber front stuffer with a rate of twist for ball for plinking, and squirrel hunting. I was just thinking that a F, a #4 or a #3 single ball might be a interesting squirrel gun in a flinter or a caplock.
Dunno just thinkin about it.
