I had one. It was a 264LBC ( 6.5 Grendel ) with a Wilson barrel. Shooting Alexander Arms ammo Lapua brass with 123 Scenars it always held 1/3 MOA with the factory loaded ammo.......It's just something a bit different but offers great brass and IMO a superior round to the 223.

alexander arms is no joke. They make some top quality stuff.
