So I have a box of once fired Winchester Supreme brass that I shot out of my rem 700 22-250 just started reloading and have done some research on excessive pressure signs in fired brass. Well after tumbling I looked all of the brass over one of the case necks where cracked and all of the cases have a slight blunge,too be honest I dont know what would concidered bad but it is noticeable. also after I deprimed the cases almost all of the primers are flat, again I dont have enough experiance to know to what level they are flattened but there is no longer a bevel to the primers at all and there is a small lip where the primer wall moved out. As soon as I can take some good pics I will post them. my question is should I even attempt to reload this brass or just toss it? Also should I worry about any damage this may have caused to my firearm, I have shot 3 boxes of this stuff but this is the first box that I have looked at closely.
