Loaded with Hornady's Gilding Metal Expanding (GMX) bullet, this bullet is harder and tougher than a copper bullet and also helps to reduce fouling in the barrel. Made with the same polymer tip bullet used in Hornady's A-Max, InterBond and SST rounds. A GMX bullet expands 1-1/2 times its original size and retains 95 percent of its original weight. The boat tail design reduces bearing surface in order to increase accuracy and consistency. This bullet gives hunters an expanding monolithic bullet that delivers ultra-flat trajectories and devastating terminal performance.
