NEWS FLASH!!!
While over on a primitive gun forum the boys over there may have given me an answer to how the barrel got bulged. It turns out I may have used my starter to get the bullet down the barrel and then forgot to ram it home.
I got the starter out and lined it up and sure enough, it matches the bulge. At least I know now how. But it doesn't make it feel any better. Somehow I got interrupted during my loading process and didn't finish the job!
Am I just stupid or just getting old?????
