I'm reloading 9mm and new to reloading. I used a Lee Auto Prime to seat 100 primers tonight, and measured every one afterward. Most were in the .003-.005 range, but about 10% were below .003. These I set aside and reseated until they were at least .003. Seating the primers went very quickly, but measuring them all is a pain. Is this something I should be doing, or am I overdoing it? Would it be unsafe to shoot rounds where the primer is seated at .001 or .002? How do some of the more experienced reloaders out there do it?
