The Grendel II, and other variants like it, are reamed without the signature compound throat of the SAAMI Grendel.
Try not to confuse this with the term "Type I" or "Type II". As bwaites described above, that only refers to the bolts.
Irrespective of the chamber, though, you can use a caliper to measure the bolt face depth to see if both of your bolts are at .136" or at .125".
Ahhh now I think I get it. Never realized there was a difference in the chamber as well.
So, basically, even if the bolt face is the same on both bolts, one still has to worry about the chamber and headspace issues?
