Over the course of nearly 60 years the AR-15 has been with us, some 65 recognized cartridges have been designed specifically for it. Most are wildcats based on the original .223/5.56 case; some became relatively popular as such and some went on to achieve SAAMI recognition and loaded commercially by at least one or more ammo manufacturers.

Others sought to base their creations on fatter cases like Remington’s 6.8 SPC, .220 Russian and .284 Win., all of which can hold more powder than the 223/5.56.

The latest cartridge designed around the AR-15, though not limited to it, is Hornady’s 6mm ARC (Advanced Rifle Cartridge), which is already on dealer shelves as you read this. The 6mm ARC was developed by Hornady for the Dept. of Defense, who wanted a cartridge that had better long-range capabilities than the 5.56, yet still fit the AR-15 platform. The ARC certainly does that.

Based on the 6.5 Grendel case, the ARC has a .441” rim diameter, the same as the .220 Russian and the 7.62×39. Other than the neck diameter, the differences between the ARC and Grendel cases are so slight you’d be hard pressed to see it even in a side-by-side comparison.

Both share the same 30-degree shoulder angle, but the Grendel’s body length i.e., the base to shoulder/neck juncture, is .030” longer. Neck length is also in the Grendel’s favor, but only by .010”. For all intents and purposes then, the ARC is essentially a necked-down Grendel with minor dimensional changes.
