Once-fired-brass for 9mm. One of the most common rounds around, able to be reloaded again and again. These are range brass that have been hand sorted with some inspection for major issues and then boxed up for your use.
We”ve hand sorted these (me and my kids). Besides sorting them by type, we’ve removed brass that has damage to the mouth or any with damage on the side wall. While we may miss some, we cull about 5% of our stock if that gives you an idea of the quality.
