9mm marked AMMO LOAD
this brass has a reinforced base that has a shelf for the bullet to sit on
this reduces the powder chamber so your favorite load is too hot for this brass
also someone else posted that the brass separates where the shelf is after just 1 or 2 loadings
.223 Norinko brass had a "j" on the headstamp old stuff but people are breaking out their long term storage ammo
primers just fall out of it on the first load
