Hornady Gliding Metal Expanding Rifle Bullet .270 Caliber/6.8mm .277 Diameter 100 Grain GMX

Expanding Monolithic bullet. Constructed of Gilding Metal. Premium polymer tip. Designed to expand to 1.5 times their original diameter and retain 95% of their original weight. Ten degree boat tail and double groove construction. GMX bullets share the same ballistic coefficient as their SST and InterBond counterparts so hand loaders can use the three interchangeably and maintain the same exterior ballistics.
