Just bought a beater double on GunBroker which I want to modify slightly to keep at the top of stairs. The picture looks like it's got a small dent in one of the barrels. Never dealt with that before, but the thought occurred that firing one or two steel shot loads may straighten it out with minimal barrel wear. Has anyone done this before? Should I use a 3" load with large shot?
