I disagree how the how liberty deal was handled by them. but having a different throat option in my mind is a good thing. being able to always seat out to at least mag length is a great thing. If accuracy was proven in the grendel II I would honestly rather have that chamber. so far its not been proven yet.
There IS a spec for throat length, what has been repeated and repeated does not make it truth. Dave Kiff considers the throat part of the spec, as does AA, Hornady, Lilja, Precision Firearms, etc. Only Satern has stated that it isn't.
The SAAMI Grendel chamber has a .5 degree cone into the throat, in comparison to standard throats which have a 1.5 degree.
The go/no go gauges also work for the 6mm AR, the 20 Grendel, etc. They only determine headspace, the point on the shoulder where the datum is.
I can seat all the regular Grendel Bullets out past mag length in my Satern Cut Rifled Grendels. There is plenty of room to do so. I can seat 130 Bergers out there too. For single loading, I've run the Bergers out to 2.32 COAL.
