I think it kind of depends a little. There is a spec difference between Nosler 280AI brass and taking a 280 Remington and fire-forming it in a 280AI chamber. Seems like I remember reading where Nosler's dimensions had a slightly shorter body on their case compared to what some 280AI dimensions have. But, since the .06 case is shorter in each instance, then yes. I was mistaken about it depending.
So, you can take 30.06 Lapua brass and blow it out to a 280AI body wise with the neck reduced.
