Re: ptr rifles?
I'm at 4 reloads on my current batch of brass fired from G3s, and there's not really much wrong with it. The G3 isn't exactly "kind" to brass, but assuming you can find it in the bushes 40 yards away, there's no reason it can't be reloaded. Sure, the side of the case gets dented, and the extractor kind of tears the rim a bit when the brass smashes into the ejector, and maybe the case mouth gets a little ding in it, but it's not like it can't be reloaded.
All too often, you'll hear people online saying things like "the chamber flutes destroy the brass", which is just false. Also, I'm currently using Remington brass, which all the online gurus will tell you is too soft for G3s. Based on the current condition of my brass, I have no reason to believe these won't last another 3 or 4 firings, but I'll probably toss them then.
