Thank You GT!
I'll send it your way

I just recently acquired the gun so my guess is a squib round caused the bulge. I wasn't going to worry about re boring the barrel, because I don't think it will make that much difference in how the gun shoots. Unless someone can tell me there is a safety issue.

Rich,
I have never heard to the tool you speak of, but if I used this tool would it not change the dimensions lengthwise also ?

Thank you everyone for your in-put and help

Jim
