"One thing I know for certain about stuck cases, if you stick one you did not use enough lube regardless of the brand. follow the 2% rule ;) "
Absolutely. All of the wild web guesses about why cases get stuck, from case or die brand, brand of press, which way the wind's blowing, failure to lube INSIDE
the necks, etc, matter not, cases stick for ONE reason; insufficent lube, usually on the lower, thicker part of the cases; most everyone puts plenty (or too much) on the upper part.
With 1Shot it's usually because the user failed to shake the spray can before use and/or didn't allow time for the carrier to evaporate and/or failed to run the first case lightly into a totally clean die before the first sizing effort.
Funniest story I've read about case lube is one guy saying an RCBS tech told him not to use Imperial or any other wax lube in their dies because the wax gets thick and rubbery so the cases are effectively glued in! Goodness...
