I just built a grendel using this barrel. It shoots the factory Hornady 123gn amax just fine and my 90 tnt hand loads great! I shot a 1/2 group at 100yrds with it the first day. Havnt had time to do much more work with it, but so far im very happy with it. From what I measured from the neck its a grendel chamber.
