May be old news, but no searches spoke directly of this.
I was having some binding/rough priming issues with my press lately. What I determined to be the cause was the primer punch is being forced slightly off center when priming due to the dimple in the press. To be quick, I disassembled the punch and used 320 sandpaper followed with coarse then fine steel wool to polish the roughness out of the finish. I then chucked the nut in a drill and lightly polished it too. Reassembly and a blast of brake cleaner and oneshot later, it is priming like never before!
Your experience may vary, but this made a very noticeable improvement in effort required to seat primers on my press. Next I may fix that dimple using ideas from the other threads here.
