Hornady Black MonoFlex .338 ARC 170gr, 20-Round Box

Hornady Black .338 ARC ammunition (brand part no. 82273) loads a 170-grain MonoFlex bullet built to run reliably across the range of platforms chambered for this cartridge. Hornady designed the MonoFlex tip to flex on impact, driving into the bullet’s core to start expansion whether the round is fired from a bolt gun, gas-piston AR, or a suppressor-ready host. The BLACK line is built and tested across direct impingement, gas piston, and inertia-bolt actions so the load performs the same regardless of platform. High-quality cases, primers, and propellant keep ignition and pressure consistent from round to round. For shooters running .338 ARC across multiple guns, this is Hornady’s do-everything load among its rifle ammunition.
