OK I think this will show.
I have installed the 0.248" OD shim in the chamfer of the primer pocket. That is a far as it will go without pressure to push it down to the primer shelf. A dead primer works very well as the punch to drive the shim to the bottom. As it goes down it compresses the ID of the inner circle a bit to fit the walls of the primer pocket.
