.338 Arc: Advanced Rifle Cartridge

The .338 Arc is a specialized rifle cartridge designed for long-range precision shooting and hunting. Developed to bridge the gap between .308 Winchester and .338 Lapua Magnum, it offers excellent ballistic performance with manageable recoil. The .338 Arc is known for its ability to maintain supersonic velocities at extended ranges, making it a popular choice among long-range shooters and hunters pursuing large game.

Development and Characteristics

The .338 Arc was developed by Advanced Armament Corporation (AAC) in collaboration with Hornady Manufacturing. It was designed to provide superior long-range performance in a more compact package than larger magnum cartridges. The cartridge is based on the .300 Remington Ultra Magnum case, necked up to .338 caliber and shortened to fit in standard-length actions.

With its efficient case design and ability to use long, high-ballistic coefficient bullets, the .338 Arc offers impressive ballistic performance. It typically propels 250-300 grain bullets at velocities ranging from 2,700 to 2,900 fps, depending on the specific load and barrel length. This combination of bullet weight and velocity results in excellent energy retention and wind resistance at long ranges.

Applications and Adoption

The .338 Arc has found favor among long-range competitive shooters, military and law enforcement snipers, and big game hunters. Its ability to deliver accurate shots at extended ranges while maintaining sufficient energy for ethical harvests of large game has made it particularly popular among hunters pursuing elk, moose, and similar-sized animals at longer distances.

Several rifle manufacturers have embraced the .338 Arc, offering it as a chambering option in their precision rifle lines. The cartridge's compatibility with standard-length actions has contributed to its growing popularity, as it allows shooters to achieve magnum-class performance without the need for specialized, longer actions.
