Ben - Cutting it back to 22" tubes for RB? BTW - Lt. James Forsyth says to shoot well with both shot and ball, the barrels need to be 30" - but for a ball gun only, they do well with 22" barrels. Seems for him, the bigger the bore, the shorter he liked the barrels. He was talking about muzzleloaders, but the same rules apply. The longer barrels are needed for the shot.
