Flintr - you forgot the M42's & M47's in .69 - both were smoothbores, but were certainly 'guns'. I really liked the M47's lines for a hunting rifle- cap-gun of course, that late. Rifled, they would be superb - with patched RB, of course. for that purpose. Once rifled by the gvernment, the military issued 730gr. Minnie's with 70gr. rifle powder for them, ranked by those who used them to advantage as being more accurate than the .54's or .58's.
