I have a 20” Remington Wingmaster 12 gauge barrel that was used for training. It has a threaded 1/8” hole in the left side of the barrel 2 1/4” from the breech face. It had a small bolt screwed into the hole that extended into the barrel to stop a round from being fully inserted into the barrel. I am wondering if it would be safe to fill the hole with an appropriate size set screw and spot weld it in place?? The hole is in the thinner part of the barrel About 1 1/2” ahead of the brass portion of the shotgun shell. Any ideas??
