Ed you really area a moron aren’t you? Have you every looked up what factory pressures are? They all run high enough to operate a dirty, semi auto. Even the 3/4 ounce loads are running 9,500 to 11,900 psi. Saying light loads, or low brass shells is a completely dumb thing to do. It is pressure, not the pay load, not the velocity, not how tall the brass is. By your logic the old Active loads ought to be best because they had the very least brass height you possible could have, none. Payload and velocity might be important to recoil but have zero effect on pressure. Please block me and stop responding to my post. You are becoming a waste of keyboard clicks. You bring nothing to any post that I can see. Go back to whatever board you came from, assuming they will have you.
