Smashed primers

Good morning,

I’m loading 9mm on my super and I’m getting an excessive amount of smashed primers that are failing to enter the primer pocket at all. As I’m observing the priming stage I can see when it’s going to happen. The case lifts up on the outside edge of the case plate (yes, it’s the right case plate). I only run small primers on this machine so it’s not a large primer punch. I’ve adjusted the Swager up and I’m getting a solid Swage on the primer pocket.

I’ve read a couple over post and Dillion has mentioned a 1/8 rubber ring. I’ve looked through my manual and I can’t find where any rubber ring would be. I got my machine from Dillon in 2013ish. Thank you for your help

On the rear of the primer slide, either you have a brass roller attached to the slide by a small bolt, or on earlier machines, a steel roll pin with a rubber sleeve pressed over it. The rubber sleeve is a short piece of 1/8" automotive vacuum hose.
