Truthfully, just measure the HS. If it is .132 the Go-Gauge will work at the highest end of tolerance's. If its .130, the go-gauge won't work (let the bolt turn and lock to the barrel extension). I even removed the extractor to make sure that was not interfering and no difference.
If a bolt HS is .130 they are non functioning bolts with the Grendel and need returned or buy a .135 bolt from Maxim and then it will work. They do function with a Go-Gauge and a correct head spaced bolt (.135) and if the Go-Gauge works, should be fine. Once I used a .135 bolt with my barrels the round chambered and extracted fine on both Liberty and Brownells Barrels. Seems as if each barrel needs confirmed by a 2 step process.
Now if you have a Maxim bolt with the rings on them it should work with a Go-Gauge but if the bullet gets stuck, it is a different issue and you might want Mark to help out or send it back. Mark did say the one he looked at had a short throat and thats a different issue.
