Meet the new 6mm ARC, the ‘6.5 Creedmoor for gas guns’

Nebraska-based ammo maker Hornady on Wednesday announced a new short-action cartridge designed to push the limits while at the same time big name gun makers unveiled rifles for it.

Based on the 6.5 Grendel case, the new SAAMI-approved Hornady 6mm Advanced Rifle Cartridge, in a nutshell, was designed for a military user that wanted a round delivering comparable ballistics to a .308 Winchester from an AR-15 platform.

“The 6mm ARC began with a simple question: What can we do with today’s technology to maximize the performance of the AR-15 platform?” said Hornady Ballistician Jayden Quinlan. “We subsequently modeled and tested a variety of designs in different calibers until we were able to produce the most flexible cartridge possible within the limits of the AR-15 system.”

Reports are that the 108 gr. ELD Match bullets leave the 18-inch PROOF Research match-grade stainless steel or carbon fiber barrel on an AR-15 platform at over 2,630 fps, remaining supersonic past 1,000 yards.
