I'm selling a .22 and the last time I shot it I was using Super Colbris. A potential buyer asked me about the bore. This morning I shined a light down it and was puzzled because I didn't see anything. Turns out there was a round stuck 4 inches from the muzzle I'm glad (1) I didn't shoot it again, and (2) that I check. I always check the chamber but I never thought about this. Just a heads-up to anyone shooting fairy loads.
