I shoot PPU brass through my .243. It is soft and only makes it 5 or so firings but I normally lose/toss it by that point anyways. For the price, I don't mind the short life.
So I apologize for hijacking the thread but what G7 y'all running in your Kestrels for these 140 ELD-M's. I have seen conflicting numbers on threads here and the published .326 doesn't seem to line up for me.
