To further our mission of creating brass for shooters by shooters, our in-house ballistician has begun providing AMP Aztec Codes from an AMP Mark II Annealer for as many of our lots as possible. He is quickly working to process as many lots as he can. Our ballistician has also listed some other critical dimensions from each lot of casings. Going forward, we will work to include all future lots of casings in this database.
All data is available in the spreadsheet below, and is updated as frequently as possible.
