Why? It's not like I am so poor that I have to salvage the lead and brass, and getting out a kinetic puller and aggravating my shoulder isn't worth a box of brass or lead. If I had 100 rounds of .44 magnum, that would by worth it. I stripped a couple pounds of shot from a bag of mixed shells that a relative dumped on me. Just last month a couple rounds of .308 were lying under the bench where I go. It's privately owned, very few members. I usually clean up when I'm through. Pull old targets, collect trash, collect empty hulls, there are always live rounds somewhere. Pulling these things isn't worth the time just to get a few grains of melting lead and a random piece of brass from God knows where.
The time I dumped a bunch of 9mm handloaded I had a good reason. They were at least twenty years old, lead, wouldn't feed properly in my glock, and were military brass. I didn't want to shoot them, I didn't want the brass, and a pound of lead wasn't worth a half hour of work. I didn't even think that it was a good idea to salvage the primed brass for scrap.
I'm just different. I found a twelve pack of beer of unidentified age and unidentified source in a cooler a few years ago, I didnt remember buying it. I'd like to say that I left it on the street corner for the local booze hounds, but I popped the tops and put it into the recycle bin. If I had set it on the corner it would have been gone before morning.
