[QUOTE="yawn, post: 1528103, member: 13540"] Ha ha, depends on how good the maths is I suppose, one decimal point out of place can have amazing consequences. Yes Edd that is my position. Gunsmith talk has an example at the beginning of this thread. Showing both the SAAMI and traditional chambers then swapping the chamber gauges around proving they are actually the same. No one has yet pointed out where or how they are wrong. I thought it was a little over complicated though and took a more basic approach. This whole discussion is around the nosler spec being .014 shorter so if you use Nosler 280ai brass it in a traditional ackley chamber it will grow by .014 and maybe create case head separation issues. Back in the beginning I was like a lot of guys just happily burning powder in my 280ai. Then I saw the alert that I was using the wrong brass for my traditional chamber. But I had no issues at all. The nosler brass wasnt gowing, in fact it was a little tight if anything and fired brass was the same base to shoulder length as new. So I rang cooper and confirmed I did indeed have a traditional chamber. But still that made no sense according to the -.014 theory. So after all the reading and internet chatter I bought a 280 rem go gauge and yes it confirmed it, its a correctly head spaced traditional ackley. I have checked more than a few 280i chambers now and results are always the same plus or minus a couple of thou. So if nosler SAAMI brass does not gain any length in a traditional chamber, if the 280rem go gauge behaves the same in both SAAMI and traditial chambers how can there be a difference? Again, ,these are just more words on the internet and wont convince anyone that has already made up their mind so don't believe me , test for yourselves, its not hard. phorwath Im sorrry someone hurt your feelings on some other forum but it wasnt me and I think you would do better to drop the attitude.
