Re: All my Remington Shotgun barrels are bulging. Anybody else with this problem?
Another thought. Did you ever replace the tubes? Are they actual rem choke tubes? It may sound silly but win choke is the same diameter and pitch, just shorter. Make sure the chokes are screwed all the way till the mouth meets the base of were it is tapped. Some people make the mistake of just turning them in till the muzzle is flush with the tube.
