The trick to adjusting the decapper is to just tighten the decapper clamp enough so that the decapper will push out 90% of the primers, but the very stubborn ones will cause the decapper to slide up through the clamp. Start with the decapper clamp just tight enough to keep the decapper from falling out the bottom of the die. Try to resize a case. The decapper will probably slide up through the decapper clamp. Tap the decapper back down flush with the top of the decapping clamp, tighten the clamp another 1/8 turn, and try again. Repeat until you successfully deprime the case.
