The Nosler brass cannot be used in the Cooper but I can use in the Kimber, and Nosler loaded ammo can be used in both rifles. Boy Nosler created a mess in my opinion. Now I just need to find out who makes what dies ,and where to get them , I have a set of Hornady custom grade dies but I just have to find out what chamber they are for . Way to much work!!!!
Actually, Remington created the mess...Remington's custom shop started chambering rifles with a .014" shorter shoulder height based on a screw-up when they ordrered the reamer (that's what I was told), and that's where all the issues came from. And then somehow Nosler got involved in the screw-up, then they used that chambering for their SAAMI spec design, then blah blah blah, all this bullcrap later....And we're at where we're at now.
Personally, if you're unsure which chamber you have for both, go buy a bag of 20 .280 Remington brass. Load 10 for each gun. Shoot the 20 brass, and keep them seperate from each other. Then measure headspacing of the fired brass, and you will have your answer.
Or you can take both of your rifles to a competent gunsmith and have him check the chamber headspacing. If they come out the same, then you're good to go to buy Nosler .280 AI brass, and just FL size them each time, so it won't matter.
But I also feel your pain of having multiple rifles in the same caliber. Which is why I keep seperate brass seperate for different rifles. And I write on the reloading label which rifle the brass was shot out of, so I know which is which. Plus, that lets me know which rilfe likes what load, so I makes me a (sort-of) load log book.
Sounds like a pain in the ass, but it's not so bad once you get the hang of it.
Plus, each rifle will like different loads, so I'd keep those brass seperate anyway, after fire-forming.
