.338 ARC brings magnum-level ballistics to modern AR platforms, marrying a compact case design with high-BC bullets for extended-range accuracy and controlled expansion on elk, mule deer or prairie dogs alike. Choose polymer-tipped match rounds for pinpoint precision, soft-point hunting loads for deep penetration, or copper-solid projectiles optimized for barrier resistance. Handloaders appreciate the uniform brass and consistent primer pockets for tailored charge development, while factory offerings from Hornady and Federal ensure dependable ignition in bolt-action and AR-10 rifles. When you’re ready to stock up, compare .338 ARC ammo, purchase .338 ARC cartridges or shop .338 ARC rounds online at Sportsman’s Outdoor Superstore—secure checkout, competitive pricing and fast shipping make it easy to get your favorite loads on the shelf.
