[QUOTE="J E Custom, post: 1532733, member: 2736"] It would have been better to call the Nosler something else because re loaders and wildcatters had been loading the 280 AI for many years and using standard 280 Rem ammo to safely fire form the 280 AI (Ackley). There were many shoulder variations from 30o to 40o but the case body to neck length never changed. One of the reasons that they called it the 280 AI was there were no listing in the SAMMI specs for it and all they had to do was submit the original dimensions to SAMMI and request that it be included and call it their cartridge and start manufacturing formed ammo and brass for it. But they chose to change the dimension and create a major problem. I have always liked and used Nosler products, but for the life of me I cant grasp why they would do something like this. I noticed that some are still saying that you can shoot 280 rem ammo/brass in the Nosler version and they are right You can but not safely and for one or two firings but with the difference in length the case is stretched .014 to .018 after the first firing and the damage is done to the case. just because you can fire a different cartridge in a chamber, doesn't mean you should. I have seen many wrong cartridges fired in the wrong chamber and the person got away with it, without injury.to them selves. but the case was ruined and in some instances the chamber was damaged. The 280 AI and the 280 SAMMI AI are two different cartridges thanks to Nosler and are not interchangeable. "Period" . No good smith would set the head space at .014+ and essentially that is what happens if you fire a standard 280 Rem in the new SAMMI chamber. If a person can read and understand the SAMMI chamber specification, it clearly shows the difference and when you add .003 thousandths head space (Normally max) you can have up to .020+ clearance in the shoulder. If one can understand that the two cartridges are different, It should be easy to know what ammo to fire in what chamber. J E CUSTOM [/QUOTE]
