It's also not a bad idea to stand them all up and look for short ones. That'll sort out the 9x18 Makarovs. A lot of us that shoot 9x18 convert 9mm Luger cases so you can't necessarily trust the headstamp alone. I try to recover all of my converted cases but they do get away sometimes. I've read a few reloaders comments that they run into these converted cases every once in a while.
