Hey John,
Any one other than LBC making the 6mm Grendel barrels? Barrels that shoot, that is....
David - guessing you meant Black Hole Weaponry / Columbia River Arms? They are the ones making the 243 LBC (and 264 LBC) chambered barrels. I have one of their 24" 243 LBC barrels and am very happy with it, would buy another from them again, but there are a number of different places making 6mm Grendel-based wildcats. Some are a straight necked-down Grendel like the 243 LBC, while others like the 6mm AR Turbo etc are slight variations. You could take a look at 6mmAR.com although some of their load data on the site seems a bit lacking.
And of course the 6mm PPC is almost the same thing; the LBC/Grendel case just has the shoulder pushed .070" farther forward and is mostly designed around no-turn necks and heavy long-range bullets.
