[QUOTE="25WSM, post: 1777516, member: 38048"] All the hoopalhoop that happened when Nosler made Sammi 280ai brass and had to use a datum point. Not the neck shoulder junction like PO did. People still think that nosler brass isn't 280ai. But it fits perfect in every 280ai chamber I make. You are correct that the datum line is longer because if you blow the shoulder forward and the datum line follows it has to be longer. The PO Ackley Improved is . 004 shorter at the neck shoulder junction only. That is why an unfired 280 will snug up in there right around that point. Sometimes you can go blue in the face trying to get that in someone's head. 280ai probably the best one he ever did. Shep [/QUOTE]
