Where may I find the SAAMI Spec?

[Drifter]

I hope they're referring to the manufactured diameter of the neck, with a bullet not seated, but their other 6.5mm cartridge diagrams all show .295" for the 6.5 Creedmoor, .297" for the .260 Rem, .297" for the 6.5 Swede, .295" for the 6.5x54 Mannlicher-Schoenauer, .297" for the 6.5x52 Carcano, and .298" for the .264 Win Mag.

Is brass thicker on those other 6.5mm cartridges?

Just trying to make some sense of it...

I thought saami was really about chamber dimensions ...
as far as neck dimensions on the brass, it will change in wall thickness
as pressure flows material forward thus changing diameter
