I think that's why the opened up pockets are on the loose side. They can easily be tightened slightly by putting the case over steel rod in a vice to act as an anvil, and then taking a drift punch and hammer lightly to the edge of the pocket. Have a spent primer in place and push it out or wiggle it to help you feel when you are hitting just hard enough to make it begin to rub. You might need to hit three spots in a rough triangle around it to go as far as you need to, but trial and error should get you there.
