With a serious bulge at the breech where the pressure is at its peak striking off a bulge would be a very bad idea. The metal has already been stretched beyond its elastic limit creating an unknown variable. My eyes and fingers are much too valuable to attempt that type of repair. I have successfully removed bulges further forward in an area of the barrel where the pressure has dropped substantially by pounding down as much as possible and then striking off the high spots. I am unsure if this is the gun I think it is....if so it has been in my shop a couple of times and a safe and cost effective solution has not been found so far. Fitting a used set of barrels will most likely be the answer as the amount of work to fit a NOS set is cost prohibitive in most cases. They require many many hours of careful fitting.
