I can't believe how they stuffed shortened 6.5 grendel cases with such huge bullets up to well over 300grains. To see a round with a bullet larger than the case is just crazy to me. Not too mention the actual range in bullet weights is intriguing as well.147gr to 307gr out of the same rifle or pistol is a win in the design and the manufacturing process. To get such a range makes this probably one of the most versatile calibers on the AR15 Platform. May have to get me one of these just out of curiosity more than anything. If I don't care for it, then a simple barrel and bolt change is all that is needed to run other ar15 calibers.
