Both dies are fubar'd.
I'm using Redding Imperial wax, at one point so much I crumpled the shoulder of the case.
What is going wrong?
Reading over this thread, I'm amazed at how One Shot is considered the saving grace. Looking at other forums, One Shot has been the greatest villain in stuck-die incidents, although the mis-use of spray lubes in general (not allowing them to dry) should really be cited. By comparison, Imperial is typically considered the solution. Case in point, one poster told of having broken two presses, one Hornady (the steel handle) and one Rockchucker (the cast-iron lower platform), before switching to Imperial. Seems he hadn't been letting the One Shot dry. He was sizing LC 308 brass.
I have a different take here. Sounds like the possible culprit is not following the die mfr's instructions to clean the dies before using. A preservative coating left on a die guarantees sticking, regardless of the sizing lube applied. I've never considered a spray-on lube to be the solution to any condition other than for ease-of-use.
