My eyeball test is to take a handful of cases and put a known 380 case between opposite hand's index finger and thumb and pass over the cases looking for a size match. That goes pretty fast. Usually about 2 or 3 per 500 get past the eyeball test.
The ones that get past my eyeball test get caught when sizing them via the 9mm shell holder: 380 cases slip out of the shell holder and get set aside.
Depriming doesn't make any difference since I use a universal depriming die for everything. I deprime, clean, sort, then size.
