Grendel II chamber

[bwaites]

so the gap rifles you mentioned you still call them 308 and 260 but the throats are specific to the bullets you shoot are they not still 308 and 260 chamberings?? I am not defending liberty barrels in fact I returned my barrel for a shilen. The problem centered around not being able to chamber factory ammo and that is a valid problem.

The problem is that if you buy a FACTORY standard .308 Winchester (to use the full name), you expect that it will function with ANY factory ammunition, and it will. Has anyone here ever heard of a rifle that did not do so?

When you order custom rifles, the fact that it is being made specifically for you allows you to customize the barrel to what you WANT, not what the standard is.

If the standard accepts all .308, then your rifle may or may not do so. (I've seen a few AR10's that were so loose they almost could have accepted a 30-06, it seemed!)

Is it still a .308, yes. Is it still a .308 Winchester, NO, most emphatically NO. It won't accept all the factory .308 Winchester out there, thus it is not a .308 Winchester. Anyone who sold such a rifle WITHOUT specifying the difference would be liable for whatever happened when someone shoehorned a factory round in there and had a "kaboom".

It's not about defending anyone, its about the standard that is the 6.5 Grendel. That standard calls for a very specific compound throat. If the chamber does not have that throat it is not a 6.5 Grendel, it is a variant, just like a .223 Wylde chamber is a varianat on the .223, or any of the .308 tight necked variants that precision shooters like.
