[QUOTE="yawn, post: 838328, member: 13540"] Jerry thanks for putting in some time here but its really just more of the same. Yes there are two sets of gauges , shown here in the only attempt to prove or disprove the difference that Iv been able to find. [url]https://gunsmithtalk.wordpress.com/2012/07/17/280-ackley-improved-emperical-headspace-test/[/url] So have they made a mistake?If so how have they got it wrong? Everything else on both sides is just anecdotal to date. But assuming there is a difference then using the old chamber will carry possible case head separation risks etc if using nosler 280ai brasss/ammo but if using the supposed shorter saami chamber then any brass or ammo should be a good fit ( nosler) or slightly to long for the chamber (all standard 280rem )so the only issue would be that the bolt may not close?If I understand this corectly using the shorter saami should carry no risk as if the bolt will close on the new brass then it should be held snugly by the shorter chamber and give no case stretch? None of which should be a substitute for good fireforming practive of course. [/QUOTE]
