JMHO, but I can't see a valid reason for anything over 7 or 8000psi in the 12ga. If you want clean barrels and action, then yes. But most of us here talk SxS's, and many of us old SxS's, and some of us with Damascus barrel SxS's. I don't mind a little unburnt powder in the barrel. In the warmer months my reloads are under 7000psi, and in the winter when it gets below 15 degrees or so I up it to around 8000psi. Paul Harm
