I finally got my head space comparator , I verified 4 fire 243 Remington brass cartridges measured 1,616 exactly, my resize cartridges' checked 1.614 . sometimes I get lucky.
I spot check the resized cartridge neck & body with calipers all good to go. I purchased the Lyman electric trimmer for bottle necks will be next step.
received my OAL gage & bullet comparator kit, and waiting for my modified 243 cartridge to arrive. In addition I will use a fired brass and head seat a bullet with a slight press. and use it to compare with the gage. I wish they had not broken the inside edge of the head space comparator , should of left it sharp. On my similar designs I would leave the edge sharp and always worked well.
