Primer pocket crush:
I am only guessing but it would appear most reloaders are exempt from perimeters, I have restored worn holes with bushings and or sleeves that did not have a crush fit = to the difference between the inside diameter of the primer pocket and the outside diameter of the primer, so I believe there is a problem with the method used to measure the hole (primer pocket). Some of the holes the holes were bored out from 4" to 4.250
I have used a heavy press to push bushings and or sleeves with a .002 thousands crush, the difference in measuring? I use an inside micrometer or a transfer or a ball micrometer or a blind hole micrometer, but a .210 primer is not going to go into a primer pocket that measures .199.
Installing a primer is lik-en to installing a welsh plug, core hole plug or freeze plug, I have installed bushings and or sleeves with a 10 pound sledge hammer, and no I did not swing over head, that is too much work I used the drop method as pick the hammer up and drop it, and there you go, if the sleeve does not move I measure again THEN get a bigger hammer, swinging like John Henry can cause peripheral damage
Had a friend call me and ask if I knew what a wedge head was, I answered with "Don't tell me. let me Guess...you....."?
Tools that could be used. primer pocket uniformer and a military crimp remover tool BUT, I would suggest the reloader measure the outside diameter of the tool first, to avoid removing the crush and or interference fit between the primer pocket and primer.
