Hornady Gilding Metal Expanding Bullets 30 Caliber (308 Diameter) 165 Grain GMX Boat Tail Lead-Free Box of 50
The gilding metal 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. Their boat tail design reduces bearing surface in order to increase accuracy and consistency. This is not loaded ammunition.
