Hello to all, I'm new member,glade to be hear!
I have a question to all you reloaders, the other day I was at firing range and measured a factory round ( PMC) a 223 with my RCBS mic gauge and it measured .00 as expected,
after firing said round , I measured case again with RCBS mic gauge, and came up with .02 less??
I can't under stand this, should it be on plus side ?
how can you keep firing same case and not bump size it? Normally when you fire a case several times it expands, you eather trim it and or bump sholder back !!!
Thank you in advance for responding to my request.
