Swap em around. The original "280AI" was/is the 280 Remington Imp 40*. The "280AI" that was made by Nosler and given SAAMI specs is known as the 280AI. Dies are also marked accordingly. My AI was the Rem Imp 40* version. And yes id go with the SAAMI spec version were I building another. 140 NAB and VV N165 really shines from a 24" tubeDvldawg said:Great cartridge, but do your research, as there are two versions..
