The Hornady Black .338 ARC 170gr is a specialized, versatile load designed to perform reliably across various firearms platforms, including gas-operated, bolt-action, and suppressed systems. It features the innovative MonoFlex® bullet, a lead-free projectile constructed from a copper alloy that combines the deep penetration of a solid copper bullet with the rapid expansion of a polymer tip. This "tipped-hollow-point" design ensures that the bullet begins expanding immediately upon impact while maintaining nearly 100% of its weight, making it a highly effective choice for medium-sized game and tactical applications. Optimized for the unique ballistics of the .338 ARC, this 170-grain load offers a balanced combination of manageable recoil, high terminal energy, and the consistent accuracy required for modern sporting rifles and short-barreled setups.
