Or get brittle with age? I traded for some "once fired" that I knew right away was not. Who ever reloaded them last had a dirty die. It still had some pleeting around the shoulder like you get with a dirty die. They normally shoot out but these didnt. Anyway I sized trimmed and loaded them so I could break in my newest build. But all 40 pieces are in the scrape brass bin now. This is what most of it looked like...some never even made is past sizing.
