When measure your OAL, are you keeping the caliper arm off to the side of the primer? I would assume that if the primer is seated correctly (slightly deeper than flush) it won't matter
Thanks
Good morning,
Correct. Never hurts to check more than one cartridge as well.
Lol, I probably check way more than I need to, but that's ok
Thanks!
I don't. A COAL that is off can alert me to a proud primer.
