If you ask Liberty Ammunition, there is a new King of the Hill, and I am not hearing any complaints. People are looking for bigger, better, and faster, which explains the rise in popularity of the AR-10 platform. Liberty Ammunition did not come as a "me too!" Instead it came as a "Me First!" with a production .308 round clocking at 3,500 fps. That is 2,700 foot-pounds of energy at the muzzle! Here is the full release from Liberty.
