Horrible gun mistakes/ malfunctions you have witnessed

[Nyles]

Yesterday I had a guy come into the store wondering why he couldn't sight in his Savage 111FCXP3. The scope was actually rattling around inside the rings. He then asked for 2 3/4" 12 gauge BBs, and only after I told him we didn't have any did he say "Oh, do you have any 2 1/2" shells? Apparently thats what the gun is actually chambered for."
