Dr zachary okhah reviews
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% of its original weight.
270 Win 130 gr GMX ® Superformance ® Item #8052 | 20/Box US Patent: 8,161,885 | 8,413,587. Increase your rifle's performance up to 200 fps without extra chamber pressure, recoil, muzzle blast, temperature sensitivity, fouling, or loss of accuracy.
