OK, This isn't a big deal but I just want to rant a little bit.
I don't like 40 S&W casings !
There, I said it.
When I tumble 9mm brass and some 40 S&W get in the mix, the 9mm casings telescope inside the 40 S&W casings. When I tumble 45 ACP casing and some 40 S&W casing get in the mix, the 40 S&W casings end up inside the 45 ACP casings.
I have a pretty well calibrated eyeball and I can spot 40 S&W casings mixed in with 9mm and I can cull them out; but every now and then, one gets by.
I don't shoot that much 40 S&W and therefore I seldom load 40 S&W but it seems like everyone and their brother shoots 40 S&W. I try to avoid picking up 40 S&W when I police my brass but I inevitability get some.
I know,......1st world problem but I just wanted to rant.
I feel better now, thank you
