I experience mirrors what openshooter said. I had the EGW undersized die, and during the upstroke after belling/powder charge, the funnel was "sticking" to the brass. It could have also been from the Lee FCD I was using. On my other press, which has a redding sizing die and an FCD, the brass was sticking to the FCD on the upstroke.
I've also read of one person breaking the carbide ring out of the FCD, which smoothed up the strokes. Defeats the purpose of the FCD if you ask me.
oh well, differ'nt strokes. "they got theirs, your got yours, and I've got mine . . . ."
