Are you lubing inside the case necks a bit? Or at least brushing them out nice a clean?
Sounds like you may be pulling the shoulder forward when you pull the case out of the die.
How easily is the case coming back out of the die? It shouldn't be a tug of war to get it out... lube the case necks very, very lightly on the inside and see if that helps.
