was out shootin the other day and kicked about a 100 lapua brass for my 308 it was pretty much on it last leg. it had been through the process 20 or so times the webb was pretty thin.
The next day or so i was shootin and the range master was tellin me a guy picked it all out of the scrap drum and was planning on using it.
?? I had a couple seperations on extraction and man is he in for a supprise.
The range master is goin talk to him if he come back. Really pay attention to what you pick up.

If I know my brass is on its last firing, I always crush it with a pliers before leaving it lay anywhere (or in a trash can). I certainly dont want to have anyone pick up my dangerous brass.

I like range brass, but you do have to be careful about what you find.
