Black Hills New 5.56mm 70 Gr Hornady GMX (Water Resistant)
Black Hills New 5.56mm 70 Gr Hornady GMX (Water Resistant) Black Hills Ammunition has added a special purpose load to its growing 5.56mm lineup. This load, utilizing the 70 grain Hornady GMX® projectile is designed as a “barrier blind” round, meaning performance is only minimally affected by barriers. It’s not armor-piercing, but significantly out-performs conventional bullets in law enforcement situations where officers may be required to engage deadly threats in vehicles or behind light cover. It’s also optimum for hunting requiring great expansion combined with deep penetration and nearly 100% weight retention. This loading is designed for rifles with a rifling twist of 1/7” or 1/8”. Penetration in ballistic gelatin consistently runs 17-22”, with a wound diameter in the 5”range. Recovered bullet diameter averages nearly .50 caliber.
