VASCAR2 Wrote:The barrel from Satern/Liberty has a Grendel II chamber which shoots 6.5 Grendel ammunition. The throat of a Grendel II chamber is different than a SAAMI 6.5 Grendel chamber with compound throat and .300 neck. The Grendel II chamber uses a standard tapered throat with long free bore to accommodate long heavy bullets. The Satern/Liberty barrels generally are head spaced to use bolts with a .136 bolt face depth referred to as a Type 2 bolt by Black Whole Weaponry (BHW).
I have read many good reports on Maxim bolts and are used by several vendors.
There really isn't anything wrong with either the barrel or bolt however Satern released several out of spec barrels several years ago. After this fiasco Satern introduced the Grendel II chamber implying the problem was with the 6.5 Grendel chamber design. This did not set well with many consumers and a few forum members. As a consumer you have to decide if the difference in the chamber design is important. The problem barrels were the button rifled bargain brand (Liberty) and not the Satern high quality cut rifled barrels. Satern still offers the cut rifled barrels with the SAAMI 6.5 Grendel chamber. I think Satern released the Grendel II barrels because they can be manufactured quicker and cheaper than the SAAMI 6.5 Grendel chamber.
Thank you
