The range I go to has some very attentive RSOs. When they see me start to pick up my brass they just start sweeping it into a pile for me in a large dust pan. Then they pour it into a bag for me.
They sweep up a lot more than what I shoot. Lately I've been shooting 9mm and there's always some non-9mm in the pile. A couple of .40's. A .32 ACP. A handful of .380. An occasional .45 ACP. But since I come home with four times as much brass as I went with it's not like I'm going to complain.
This popped up in the last batch. Just one of them. I've read about these somewhere. I don't think I'll reload it but if I remember they are reloadable.
