Primer hardness
LGS where I occasionally worked got in a few bricks of CCI 41 mil-spec primers, so I grabbed one. I want to compare firing pin strikes to CCI 450s. Both on fired cases and unfired just cycled through the rifle by a previously fired cartridge. Only way I can figure out is if I can find a small enough needle tip for a dial indicator or a micrometer which measures in ten thousandths with something similar.
Anyone got a better idea? This posted on other forums also. |
