Yes, just as a test
OK, interesting, I have no problem with that as its not much different then pushing with a press. But how is it factored into a head space measurement?
Help me follow along. You want to know why your brass with 49.0 gr of IMR 4064 is not expanding to SAAMI chamber dimensions after firing, correct? And if it is expanding to your chamber why the dimensions are inconsistent and all below SAMMI minimum, correct?
