I remember as a kid one of the neighbors who would get in to his fathers reloading stuff and make up rounds that would probably blow a gun apart it it was ever shot. He thought it was funny to leave these loaded cartridges at the shooting range. (I do not know if anyone ever shot them or blew up their gun.)
I refuse to shoot reloads that someone else has made.
I do not know if the round I found at the range is a reload, a factory round, or one of the type that idiot used to leave at the range.
I pull the round apart and reuse what I can or toss them in the recycle bin afterwards.
