What causes this?

Never had an issue with Lee full length but collet dies can bind and not work correctly if not cleaned and lubed . Since 1 out of 50 was the only failure I would suspect a problem with the case, not the dies.

I suspect it was too. I pulled the components and ran it through an old Herter’s FL die. Lubed the same as I do with sizing wax and that case is now miserably stuck. Got an extra piece of brass and ran it through the Lee set with no problems to round out my 50rd batch.
