I got some frontier brass. Is it supposed to be any good? Reason I asked is I had 40 sitting around, that only had one firing thru them. Since the rest of my brass has been shot so many times, I figured I would load up this stuff for my TSX 150gr testing and load workup. I didn't have good luck with the load. Wondering if the brass was good. I got from a buddy who shot light magnums from Hornady.
