SquirrelNuts, I get 2-4 firings before the primer pockets get loose. My chambers are cut to .001" headspace, or less if I can hit it. The cases themselves are easy to resize because there is very little stretching. I can't tell if the burn rate of the powder makes any difference since the primer pockets don't last. I'm going to try building a pocket swager when things slow down. I don't throw any of these hulls away.
Good shooting, Tom
