Hello all, so I recently acquired a savage model 1920 in 300 and the guy who had it before me tried to drill and tap the barrel to put scope mounts on. The problem is that he drilled all the way through and his remedy was to put a screw in and weld the hole shut. After firing it a couple times the welded hole started to crack. Not sure what to do. Are barrels easy to find or should I try welding it the right way.
