The latest from Liberty is said to leave the barrel as much as 80 percent faster than some competitors and hit harder than nearly everything in its class. This is through the use of lightweight monolithic bullets packed with an aggressive powder charge. When you consider a magazine full of 15 or 30 rounds, there's a noticeable difference, and Liberty Overwatch saves on loaded weight. Initial loads will be in 9 mm Luger, .45 ACP, .357 Mag., 10 mm Auto, .223 Rem, and .300 BLK.
