I had a box of match 308 brass that must have been shot in a very hot machine gun. All attempts to resize ended with a stuck case and I ruined 2 dies. My friend turned me on to RUSTER LUBE rapid wildcat case lube. Rub on two fingers roll brass in your hand and the first case I almost knocked out my teeth on the press the handle fell so fast. So I set out to size these 300 cases as fast as I can feed them to the Rockchucker. Two 30/06 were mixed in they went through and came out with a very long necks with little effort. No bench should be without it. J.Michael
