200 round Factory-Sealed Case Hornady 81265 GMX TAP Barrier - 5.56 NATO Optimized 70 Grain Hornady GMX in 20 round boxes
Brand : Hornady
- SKU:
- 81265(200)
The 70 grain GMX is a monolithic hollow-point, but unlike similar monolithic bullets such as the all-copper Barnes TSX, the Hornady GMX is made from gilding metal (95% copper and 5% zinc). Hence the âGMâ portion of GMX. The 70 grain GMX has a nominal length of approximately 1.048â, making it slightly longer than the 70 grain Barnes TSX. Molon posting on m4carbine.net
"...the Hornady 70gr GMX projectile...is probably as close as one can get to the fabled "Browntip" ammo, although I believe the Browntip uses a TSX instead of a GMX bullet. Arguably, the GMX is an even better projectile for its superior performance on windshields and its resistance to fouling barrels quite as much.

"(The) 70-grain 5.56 is just the medicine for those searching for a high-performing monometal round. The load features a Hornady GMX monolithic copper alloy bullet. The longer projectile offers shooters an outstanding .350 ballistic coefficient. This combined with its weight and 95-percent retention of mass after impact, the round has excellent terminal ballistics and can really reach out and touch a critter. It also gives law enforcement a solid choice for a barrier penetration. Note, the load is designed to function with 1:7- and 1:8-inch twist rates." Gun Digest
Please Note: While the 5.56x45mm NATO will fit in a .223 Remington chamber, the 5.56 is a military round that runs at higher pressures than its .223 counterpart and is not recommended to be fired in a .223 Remington chamber!
