I've recently noticed that my primers are raised a few thousandths. Firm priming pressure does not seat them any deeper. I measured everything (again) and here is what I've got: A. Pockets that measure about about .120" deep when measured with the back end of my dial caliper. B. Federal 210M & 215M primers that measure a consistent .1265" I normally uniform the pockets with a Sinclair carbide pocket uniforming tool which is at a set depth (not adjustable) but this does not seem to help. What should the depth of large rifle pockets be? And how thick should the primers be? I've been reloading for over 30 years and never noticed this before, any idea what's going on here?
