Nosler took the 280AI chambering to SAAMI to have it standardized, by a vote of the members of SAAMI they found there was Ackley's original design and a version by Remington's custom shop that was .014" shorter. To avoid confusion they changed Ackleys design by lengthening the chamber. Current production 280AI ammunition as produced by Nosler will not chamber in a genuine 280AI, they are too long!! For the people that have a genuine 280AI chamber they can use 280Rem ammo or virgin cases in there rifles to form cases. William
