[QUOTE="Lefty7mmstw, post: 791100, member: 48043"] The brass will be as good or better than the correct headstamp stuff. I've done the fireforming with pistol powder and farina and I've shot live ammo; I've gone to the latter as the pistol powder and cereal makes a mess of the barrel. Of course I did do nearly 100 rounds brass in around an hour. My old 7stw liked a mild load of h4831 with a 120 sierra for fireforming; it shot cloverleafs fireforming. My dad's stw hated that load and shot groups in the inches. You never know where you'll land until you try it. I'm glad you have changed your load to ease up on the primer pockets; working a rifle hard isn't any good for its longevity. [/QUOTE]
