.....I should add, my .223 brass is a mix of stuff. Mostly Winchester, some Hornady...some of some other I don't remember. I'm a meticulous brass prepper though, so bottom line...it's almost all the same to me. Rather, all the same to the groundhogs.
With my new .243, I'm keeping a closer eye on the brass due to the higher pressures. All Winchester brass for it so far, and no issues.
