Bullets should pass easily through the die. Oversize bullets or a die on the low limit can cause a problem. Start by removing the bullet seating plug and adjusting knob. Clean the die out using any solvent. Now try dropping a bullet through the die. It should pass through. If it gets stuck, return the die and a couple of bullets to the factory and we will modify the die to fit the bullets.
