Hornady’s .338 ARC 175‑gr BLACK HP Match is a high-performance supersonic round for suppressed or unsuppressed AR‑15 systems, offering enhanced energy, accuracy, and versatility. It’s ideal for medium-range hunting or serious target shooting when you're equipped to support .338-cal suppressors and an ARC-spec build. As ecosystem support grows—ammo, mags, bolts—it’s shaping up to be a standout option for .338 AR-platform shooters.
When compared to .300 Blackout, the .338 ARC offers ~50% more power and avoids the risk of mis-chambering into a 5.56 rifle
