I have one of the old round type.I've had it since the early '80s.No,it's not working anymore but I can't blame it for retiring;it served me so well for these 10s K rds I've primed with it(mostly .45ACP).
I didn't buy a new triangular shaped one because I've heard reports that they weren't as good as the old ones.I went to a green color one...and had problems with it since day 1.

Nope,they don't make'em like they used to!
