So this is a tough one to write up.
I'd been promising to take my kid (8 year old son) to the range for a couple weeks now, and with having Friday off it seemed like a perfect opportunity. This would be about his 12th trip to the range with me, so he's well versed on the rules and protocols, and has shot both pistol and rifle numerous times. We loaded up and rolled out around 11 and were setting up shop by 11:30. First 20 or so rounds through his Henry Youth lever action are going well and he's shooting straight paper. He decides during a cease fire and target change for the other people there he wants to shoot the "tonsil." It's a polymer reactive target about 2" in diameter that hangs down. You hit it and it swings up and drops back into place.
A note about my range: it's an old club and indoor range, and doesn't have returning targets. We use a common moving firing line so everyone has to agree on the distance. I a while back made up a PVC based target stand so I can shoot shorter distances while everyone else can shoot the full 25 yard of the range. We were using this stand at a distance of 10 meters (it's what's marked on the wall), the same distance the air pistol guys like to use.
He loads up the full 13 compliment into the tube and takes his first couple shots... miss, miss, hit! As he's cycling the action the cardboard backer that's holding it up folds over. No biggie, I'd put the clamps low so as to lessen the chance of him hitting them. The other two people there see it fold, they look at me, and we go range cold for me to trot down, move the clamps so it doesn't fold over again, and come back. 10 seconds max. As i'm starting back I hear a shot fired. I start looking at the other two gentlemen to see who's ass i'm about to rip 2 new assholes into, when I realize it wasn't a 9mm that they'd been shooting but a .22. My son's words were to the effect of "it wasn't on safe, so I wanted to make it safe while you were fixing the target!"
A note about the rifle: Henry's rifles (at least all the ones I have) have a safety position you engage from the hammer. You have pull the hammer back slightly until it clicks. That locks the trigger from working until you either cock the hammer fully or cycle the action.
He had decided while I was down range to try and make the rifle safe. However it was cocked and chambered with a live round. To engage the safety you need to hold the trigger back and SLOWLY lower the hammer, then semi-cock the hammer. That obviously didn't go as planned. After looking at the position of the rifle on the table (he never picked it up to try and safe it) I realized that about 2 seconds before the shot broke I'd been standing where it was pointed. That ended our range outing immediately.
After going over all of this for a couple hours I've come to the following conclusions:
1) People easily forget safety rules you've drilled into them, especially when they get an idea in their heads.
2) The standing club rule of TOUCH NOTHING ON THE BENCHES WHEN PEOPLE ARE DOWNRANGE isn't enough consideration.
3) Clear the breech or empty the firearm completely when going downrange and not taking whomever is with me along, and get chamber flags for .22lr caliber firearms.
4) Getting shot at really pisses me off.
I've gotten complacent about the state of the weapons on the tables. I've justified that "if no one's touching it, it doesn't matter if it's loaded, it won't go off." That stops today.
