[QUOTE="7magcreedmoor, post: 1064074, member: 48559"] There have been a pile of articles and discussions on this. As I understand it, the controversy over the Ackley variants has to do with the 40degree shoulder version, and has to do with where the measurement of length is made (datum line on shoulder) but the short version of the story is the actual chambers are the same, only the method of measuring is different and causing all this fuss. I've seen a couple vids where cutaways of both specs are shown with go gauges in them, and they interchange freely. I have a 280 AI chambered by PacNor using the "new" SAAMI spec, and I use Nosler 280 AI brass with no issues, as they advised me to do. [/QUOTE]
