.22 ARC / .22 Advanced Rifle Cartridge (Handloader issue #352)

Cartridge History

The .22 ARC (Advanced Rifle Cartridge) continues to solidify its role as a high-performance, high-velocity round designed to maximize ballistic efficiency and terminal performance in both semi-automatic and bolt-action platforms. In testing featured in Handloader issue #352, this innovative cartridge once again demonstrated its potential across a range of bullet weights and powders, delivering impressive precision, speed, and consistency—especially at extended distances. The cartridge was tested using a precision-built bolt-action rifle based on a Pacific Tool & Gauge Drakkar action, featuring a 20-inch Proof Research carbon-fiber barrel with a 1:7 twist. Optics were provided by a Leupold Mark 4 4.5-18x 52mm scope, offering excellent clarity for precise shooting. All loads were handloaded using Hornady dies in an Area 419 ZERO press, with powder charges dispensed to a meticulous ±0.04 grain tolerance via the RCBS MatchMaster scale. Test data was collected using a Garmin Xero C1 Pro Chronograph, with environmental conditions monitored by a Kestrel 5700. The setting—a high desert plateau at 5,000 feet elevation—provided a stable testing ground with moderate 6 mph wind, 82°F temperature, and 42% humidity. All rounds were assembled with resized Lapua 6.5 Grendel brass and Federal 205M match primers, emphasizing consistency. The 62-grain Hornady ELD-VT bullet paired with Accurate AAC-2230 powder stood out for both speed and precision. Top velocities reached 3,584 fps with a 31.0-grain charge, and group sizes as tight as 0.47 inches were recorded, showcasing the cartridge’s varminting and mid-range target capabilities. Shifting to heavier projectiles, the 70-grain Nosler RDF mated with Shooters World Long Rifle powder offered exceptional balance. At a max charge of 31.5 grains, velocity reached 3,126 fps with a tight 0.73-inch group, and the best group came with a 30.5-grain charge at 0.38 inches. These results are indicative of the .22 ARC’s ability to stabilize longer, high-BC bullets even at modest case capacities. For those interested in high-weight match bullets, the 90-grain Hornady A-Tip paired with Alliant RL-15.5 TS and Winchester StaBALL Match powders brought additional insights. The RL-15.5 loads topped out at 2,894 fps while maintaining sub-MOA accuracy, with one standout group measuring just 0.32 inches. Meanwhile, StaBALL Match performed respectably, with a 28.7-grain charge producing 2,861 fps and a 0.80-inch group. Throughout this round of testing, the .22 ARC proved highly adaptable to different bullet types and propellants. It’s clear that this cartridge isn’t just a niche wildcat—it’s a robust, modern alternative for shooters looking to go beyond the .223 Remington. With the ability to handle long, high-BC bullets in a standard AR-15-length action, the .22 ARC gives precision shooters and varminters alike a fresh edge. The consistent theme across all load data was excellent velocity, repeatable precision, and flexibility in bullet weight from 62 to 90 grains. Whether it's for paper-punching, predator control, or long-range steel, the .22 ARC continues to impress as a future-proof performer.
