Hornady Subsonic 338 ARC 307gr Sub-X Ammunition

What Makes Sub-X Different?

Most expanding bullets require high velocity to reliably mushroom on impact. Hornady’s Sub-X bullet solves this with a unique design featuring a long, flat-profile ogive and a flex tip insert that initiates expansion even at the low velocities typical of subsonic loads. The result is consistent, controlled expansion with excellent weight retention — delivering real terminal performance where other subsonic rounds fall short.

Why 338 ARC?

The 338 ARC cartridge is one of the most exciting developments in the suppressed shooting world. Built on the 6.5 Creedmoor case necked up to .338 caliber, it pushes heavy, large-diameter projectiles at subsonic speeds from short-barreled rifles. The combination of a .338-caliber 307-grain bullet at subsonic velocity creates a whisper-quiet round with substantially more energy and wound channel than smaller subsonic calibers like 300 Blackout.

This makes it ideal for:

• Suppressed hunting — large wound channel with minimal noise
• Hog and predator control — effective terminal performance on medium game
• Home and property defense (suppressed) — reduced blast, flash, and hearing damage
• Subsonic precision shooting — heavy bullet bucks wind better than lighter subsonic loads

Ideal Platforms

The 338 ARC is designed for bolt-action and semi-auto platforms.
