The vast majority of my 9mm loading is for combat pistol training. So I only sort out the military and crimped primers and the “sleeved” brass ( the ones with the thick walls below the bullet.).
for accuracy shooting (bullseye) I’d sort out one make from known once fired brass and develop a long line load with that. All the rest goes into the short line load. After 3 firings put it in the practice bin.
Yep - forgot to mention sorting out the crimped primer. WCC always flies below the radar but can be crimped.
Also, I run a magnet across all nickel cases. Someone got bright idea of nickel coating steel cases.
