You had according to your post no problems with Nosler 280AI brass and I have no problems with it and you can check my post here my wife has 280AI chamber 2007 and I have no problems chambering Nosler 280AI. Like you I had to fire form brass with that rifle and that rifle wasn't build to SAAMI 280AI spec but Manson reamer was used.
I'm the guy that loads 280AI with 160gr AB @ 56gr/R-17 @ 3046fps.
Had I not be able to shoot Nosler brass in my wife's 280AI it wouldn't of bother me since I fire form enough brass and I'm sure you did. When my rifle was build I send along dummy rds for throating using Nosler 280AI brass and if there was a problem first one I'd be talking to is the gunsmith.
I think had some followed your post like I did and reason I did along with JD338 on Nosler forum was for loading data that you both had and then your posting of those three cases is little odd. I think you should of given little more history on your 280AI.
Good part is your still shooting that 280AI and I'm enjoying mine also.
Do you measure your case shoulder expansion on new Nosler 280AI cases? If so, how much expansion do you get?
56 gr RL17 with the Nosler 160 gr Accubond is exactly what I use (Fed215M primers)
The problem is not that anyone CAN NOT shoot the Nosler 280AI brass in any gun, it is just that it will cause flattened primers and probably more thinning at the pressure ring. Once it is fire formed, it does not matter. Don't expect to be able to chamber a fire formed case from an older Ackley chamber in a SAAMI chamber.
What 3 cases are you talking about? Do you have a link or explanation?
I believe I outlined my 280AI history in post #4
