Dirty gun fail

No, not a dirty gun jamming on me. I have a shotgun I'm looking to trade, and today I popped the barrel off to look it over. Whoops, those 2 slugs I ran down the bore left it dirtier than I expected- more than just a patch and fast wipe down would cure. So it stayed home today. Of course, the gun shop near my parent's house actually had something I was interested in. Might have to give it a good cleaning and go back Monday. Or wait for the show next week.
