I bought a mixed bag of once fired brass from the local range and a few of the cases have PPU headstamp. I have neaver seen this headstamp before and there is nothing on the good vs. bad brass list. I whent ahead and loaded them and man, thoes things ran through my Lee dies like butter. Everything was veary smooth, even the primer seating was nice, unlike the Speer and S&B that where mixed in. Anyone ever had any PPU brass? I wish I could find some more of this stuff. Is there a way to get the primers to seat easyer in Speer and S&B brass? It's not that big of a deal just thought I'd ask.
