I usually do a decent job of sorting brass (my own + range pickups) but lately I'm thinking my "eyeball test" isn't as accurate as it once was
Specifically, 380's are sneaking into my 9MM stash and putting a kibosh on my reloading sessions.
Short of sorting brass by headstamp (which honestly I'm probably never going to do for pistol calibers) what can I do to improve my process ? What works for ya ?
