I have this 16" bull stainless contender barrel, in 32-20, made in the TC custom shop, and the last 4-5" of the barrel screws off, leaving a pencil size barrel that is all part of the rest of the barrel. What in the world could be the reason for this outer piece to come off for? Walt.
The 32-20 is an accurate cartridge but a powerless one at that. I'm thinking outer sheath for target shooting and screw it off to reduce weight for small game hunting. Like railroader said a lot of trouble for that particular cartridge. That's my inflation impacted two cents anyway.
