I ran into the same problem with 2 new type-s dies lately. Used to run the hornady one shot, but stuck and destroyed the first case. Thought it was a fluke, so more lube, same problem. Imperial wax, q-tips inside neck to lube, cleaning die then spraying inside, graphite, etc...all same result. Imperial wax was ok, but messy. My cousin recommended Dillon lube, case solved. Same batch of brand new cases went through the same die like butter. And it is only a lanolin oil and very high concentration rubbing alcohol as a carrier. I'll never go back.
