I pick up a lot of live .22 rounds at our range off the ground and out of the brass boxes. Obviously discarded whether because of FTF or other reasons.
If it was centerfire, someone would take it home and salvage it, but nobody wants old .22 rounds. More importantly, IMO, nobody cares what happens to them.
I'm fairly new at this range. When I've asked older members what to do with them I get answers like "stick it in the ground", "toss it in the trash", "I dunno".
I was shooting at a major indoor range a while back and had an FTF as one of the employees was walking by. He tossed it in the trash.
All those solutions bother me. Am I just being too fussy or do dud .22's deserve a better disposal method? I don't like putting live ammo, even an old .22 round, in the trash. What do you do?
BTW - I don't put anything in my guns that has been on the ground. That's not the answer, especially for old or mangled cartridges.
