[QUOTE="Pdvdh, post: 1296913, member: 4191"] [b]Re: 280 AI case head separation[/b] The information/alert at that link isn't written, generated, or posted by the Nosler company. It's a Thread discussion on the Nosler Reloading Forum web site, no different that this Thread is a discussion on the LongRangeHunting Forum web site. Significance being, Nosler cannot be credited as the source for any of the information/opinions/positions expressed in that Thread on their Forum. No more than Len can be credited with any of the information being posted in this Thread on his Forum. But I agree that use of Nosler's current 280 AI brass could be a mismatch for a 280 AI chamber cut to the original, pre-SAAMI 280 Ackley Improved headspace. There are pre-SAAMI go gauges and chamber reamers manufactured prior to SAAMI's adoption of their 280 AI in 2008, that could result in chamber headspace cut 0.014" or more deeper than the 2008 SAAMI adopted headspace specification. But I still don't expect excessive chamber headspace of 0.014" to result in 8 out of 10 case head separations based on the single, original firing of factory ammo. [/QUOTE]
