Some of my 9mm brass is getting up to around 5-6 reloads. I'm habitually checking each case now to make sure there's no cracking, but how long can I keep this going? I tend to stay on the low end of load data, and my recoil is relatively light, but I've never chrono'd my rounds so I really have no idea exactly where I'm at in terms of velocity/pressure.. How long can I keep using this brass? Wanna kill these ads? We can help!
