[QUOTE="Ridgerunner665, post: 959045, member: 12660"] I just read all of that...and I don't see what is so confusing. There are two reamers, gauges, etc because some makers are measuring to a different spot...the neck/shoulder junction or the .375 datum line...Ackely used the neck/shoulder junction...SAAMI uses the .375 datum line...the datum line (down on the shoulder) is .014" closer to the head of the case than the neck/shoulder junction. That could be all wrong...but thats what I get out of reading all this stuff...I don't have a 280AI just yet (very soon, with a Nosler chamber) [/QUOTE]
