I am not an expert on southern mountain rifles, or on anything for that matter, but, follow this thinking. The plain, old
southern mountain rifles were being made by "poor" people. Many of them probably forged their own barrels, along with
all the other hardware. If they forged the barrel, they could easily have made it swamped. As a matter of fact, I have
seen southern barrels where the muzzle was larger than the breech..............Don
