I might be late to the party on this discovery, but I just thought about it lately. I have this issue where I seat a primer and it goes into X amount fired case way too loosely. Usually, when I don't deprime it, it blows out or etches the bolt face.
Primers are .2095-.20105" generally. Primer pockets are .0075-.2010 generally. There is a .211" size drill bit in the Harbor Freight wire drill bit kit. Use the chuck/smooth end for a poor man's pin gauge. If the .211 smooth end pin inserts, the pocket is too big.
