I was out shooting my RIA 1911 45 that I've had for over a decade, and has gone through several thousand rounds. Shooting lead semi-wadcutters, I had a first, a round with no powder. I could tell right away something was up and sure enough the primer pushed the bullet just far enough into the barrel that I was done for the day. When I got home I used a dowel to tap the bullet out and took the opportunity to clean it up as well. When I was done cleaning, I figured I'd scope the barrel so see if the squib did any obvious damage. I was amazed to find these radial marks down the entire barrel, and some that looked pretty deep. I guess it's time for a new barrel.
