I'm considering loading cast boolits for my PTR-91, but all of my commercial and military surplus brass, is severely dented, and I don't trust it to chamber and extract reliably if I reload it. However, I don't want to purchase new brass, only to throw it away after a single use. So, my question is, how mild a loading is required to prevent my brass from being destroyed? Or, is this a doomed endeavor? I still want the action to cycle, and need a round that I can train with, within 100 yards or so (minute of pie plate accuracy would be the minimum here). I have a bunch of H4895, which I would like to use if at all possible, if only for simplicity (I use it for my other two 30 caliber rifles already).
