The SAAMI neck is .322 - .321 on the necks. Their base is .551 on SAAMI and their freebore is .0007 smaller. I have never had clickers with ADG brass in the 7SAUM and I'm into around box number 33 or so. I'll have to remember this. I also downloaded your reamer spec to save incase I do.
I run a 0.190 FB and a 0.200 FB mod saami chambers for body dimensions. Honestly I probably have 8,000 firings and never had a clicker in one. All Adg brass. Maybe I should go back to Las Vegas and go all in lol.
