6.5 Grendel II ~vs~ regular grendel.....?

[BjornF16]

Cory, I'm new here. I dont know who you think I am, but I'm not them. It just seemed weird to me that a throat change designated the cartridge a wildcat. If you go back into 10 years of 308 Winchester production barrels I'm willing to bet that between Winchester, Ruger, Remington, and Savage there are all kinds of slight throat variations.
I really know nothing about the Grendel besides the little that is available on the internet. I do know a fair amount about barrels and chambers though.
GSP, its on the print as a reference, not a headspace callout. There is no throat on a SAAMI go/no-go gage. SAAMI isn't concerned with reloaders and to the best of my knowledge (which I may be incorrect and i apologize if that's the case), pretty much all the factory Grendel ammo fires fine in the AA and "GII" chambers.
Montana, the 264 LBC has a different throat dimension (LBC-.295" vs AA, GII- .300"). LB made a change to the dimensions themselves therefore changed the chamber as opposed to making it different.

Takes SAAMI spec ammo,
Takes SAAMI go gage,
Still not a Grendel?

I guess im just a bit confused about all the fuss over a different throat.

Well...I guess .260 Remington is a .308 SAAMI round...who'd have thunk it.

Wait! 25-06, 280 Rem are apparently 30-06 SAAMI as well. Wow! I would have never believed.

.243 WIN, 260 REM, 7mm-08, 338 Federal, and 358 WIN all use .308 WIN go/no go gauges. Who cares about the throat. Since they all take the same "go gauge" they are .308 WIN SAAMI.

Brilliant!
