I havnt had any new brass in a long time. A few weeka ago I bought two boxes of factory 454 casull ammo to shoot up for the brass. One was a box of Winchester dual bond in nickel cases, the other box a box of Hornady Custom.
Half of the winchesters split around the head on the first firing...and the Hornadys all swelled around the head dramacily. Is new brass all this bad, or did I just get acouple of bad lots?
