Planned to go miss some skeet. I took my wife's cousin and uncle. My father in law asks if we will take the shotgun he has had repaired (his father's Browning ancient Browning A5) just to test. Sure.
Cousin gets up to the first stage and shoots a round. No eject. He'd put 2 rounds in which is technically a no-no but a lot of guys do 2 at a time to fiddle less with the gun. He suffers the nastiest stovepipe double feed I've ever seen and the gun is seized shut. I'm not proud of the solution and we wound up cutting out the double feed (a live shell) fron the bottom with a razor. Retired the gun for the day to go back to the gunsmith. If I'm honest it's a clunky design and I get the sentimentality but there's no reason to use it.
Cousin gets his other shotgun, a 20 gauge pump and steps up to the line. This time click and no bang. I insisted he either show me a dud or do a round count to prove a feed failure. Sure enough, 1 round missing. Now we need to assess. We have a push rod with offset handle on the range and out pops a live round. That's what happens when you put a 20 gauge shell in your dad's 12 gauge gun you grabbed by accident. This is the

of the shotgun world. Had he pumped in another live round we would have likely blown up the gun and been on our way to the ER.
Fortunately the range safety standards kept us from a disaster. It's easy to understand pulling the wrong gun from the back of the pickup after fiddling with a stoppage for 20 minutes. And cousin was able to laugh off being the dumb guy and be thankful we had a clearing procedure to prevent something bad. We then had a fun time missing.
It's a good reminder to be safe at the range and if something feels off clear the weapons and do a basic safety check. I knew what to do but it's also because I've seen a 1911 seize because 1911s don't shoot .45 GAP. I've also seen new shooters who thought that .38, .38 Super, and .380 ACP were kinda the same. Some of us might laugh but I get a little paranoid about this stuff because I might bring both a .308 and a 6.5 Creedmoor. You can have a boo-boo doing that.
I did everything right and it was still a near miss. But you're better off with egg on your face than blood.
