I just ordered a 280AI in a Montana Rifle Company Extreme X2. I don't know if you have seen one of the new X2 rifles, but this rifle has come a LONG LONG way since its earlier models. It is smooth as butter and TO ME, they are the perfect weight for a do it all rifle. Barrel is NOT pencil thin, like a lot of spotter barrels, and is built off of the Winchester style action. I know NOTHING about the Nosler, but just wanted you to know that there are other options in the 280AI besides just the Nosler. Happy hunting!!!
