I have had some of the Nosler 280AI brass on back order with Midway since April, last I looked projected delivery was January, the date just keeps moving out. My rifle is finally done and I'm forming brass form Remington 280. One thing to watch for is there are two different 280AI chambers, the traditional old one and the new Nosler version. Here is a link to a discussion on it:
