This video from American Rifleman features Hornady's 6 mm ARC cartridge, highlighting its development to offer superior ballistic performance within the AR-15 platform. The cartridge was designed to meet U.S. Department of Defense requirements for enhanced lethality and range (over 1,000 yards) without compromising the AR-15's size and weight advantages, unlike the heavier AR-10 platform or the less capable 5.56mm. The 6 mm ARC optimizes efficiency for longer, low-drag bullets, making it suitable for both military applications and civilian precision rifle shooting.
