I have some winchester WMA 13 9mm brass that I picked up today at the range. 1. Does anyone know anything, good or bad, about this brass? 2. There does appear to be a crimp around the primer, but I checked the inside diameter with my calipers and it was identical to a random case that didn't have the crimp ring. Will I have any issues seating primers? Thanks. Wanna kill these ads? We can help!
