.22 ARC

The .22 ARC (Advanced Rifle Cartridge) is an innovative addition to the long line of .22 caliber cartridges that have shaped the world of small- and medium-bore shooting. Introduced by Hornady in 2023, the .22 ARC was designed to optimize performance from America's most popular modern sporting rifles, specifically those built around the AR-15 platform. Its introduction capitalizes on decades of ballistic advancements and the need for a high-velocity, flat-shooting cartridge that surpasses the limitations of traditional .223 Remington and 5.56 NATO loads, particularly when using heavier, high-ballistic-coefficient projectiles. Drawing from lessons learned on both competition fields and hunting grounds, the .22 ARC aims to deliver superior velocity, accuracy, and energy while retaining compatibility with standard AR-15 components.

When it comes to applications, the .22 ARC truly shines in versatility. Its design makes it an exceptional choice for long-range varmint shooting, predator control, and even competition use in disciplines where high-speed, flat-shooting rounds are advantageous. Reloaders will appreciate the cartridge’s potential for tailoring loads to specific tasks, ranging from sub-MOA precision shooting to high-volume varmint eradication. In the sport shooting domain, the .22 ARC’s ability to drive heavy-for-caliber bullets efficiently out of an AR-15 makes it highly competitive for precision and action shooting matches where wind drift and trajectory are critical factors. Its robust case design, optimized for AR-15 magazine dimensions, minimizes feeding issues and maximizes reliability—key considerations for high-round-count sessions at the range or in matches.

For those targeting specific species, the .22 ARC brings plenty to the table. It is ideal for hunting small to medium-sized game, including varmints like groundhogs, prairie dogs, and coyotes, as well as small predators such as foxes and bobcats. With the right bullet selection, it can be stretched for use on game up to small deer, especially in regions where regulations permit .22-caliber centerfire cartridges for deer hunting. The high velocities and energy achievable from the .22 ARC ensure rapid expansion and deep penetration with suitable bullets, making it humane and effective for ethically harvesting game within appropriate ranges.

In terms of bullet weights and overall caliber characteristics, the .22 ARC is designed to accommodate a broad spectrum of bullet weights typically ranging from 55 to 77 grains. This range leverages modern bullet technology, such as high-BC (ballistic coefficient) projectiles, which are essential for long-range accuracy and minimal wind drift. The cartridge’s case capacity allows it to push heavy-for-caliber bullets at impressive velocities—often exceeding those possible with .223 Remington—while remaining within safe pressure limits. The case head and rim dimensions are similar to the 6mm ARC, making brass conversion and reloading straightforward for those already working with compatible calibers. The .22 ARC combines impressive external ballistics with manageable recoil, reduced barrel wear compared to overbore .22s, and the potential for outstanding accuracy through careful handloading, all of which make it a compelling choice for experienced ammunition reloaders seeking the latest evolution in .22 caliber performance.
