After watching their videos and looking closely at the velocity numbers, it has nothing to offer over the 6x6.8 or the WOA, thats been on the market for a good while. More than a few have put their name on something that was first made by others. The first 6mm on a 6.8 case I saw was by White Oak Armament in the early 2000s.
Shortly thereafter, there were a half dozen wanna be's that had the same case with their name on it. Most changed the case a thousand here and a degree there. Not offering anything in the way of real world performance gain. The original Hollinger design had a long throat to accommodate the long 6MM bullets in the matches the case was designed for. Some of the smarter varmint rifle builders shortened that throat for the lighter and shorter bullets used.
You can fool all of the people some of the time, and some of the people all the time.
