Hornady 30-30 Win 175gr Sub‑X Subsonic

The Hornady 30-30 Win 175gr Sub‑X Subsonic is a factory-loaded hunting cartridge engineered for lever-action, bolt-action, and autoloading rifles chambered in .30-30 Winchester. Manufactured with premium Boxer‑primed brass and assembled to Hornady Custom-grade standards, this cartridge provides consistent chamber pressure, smooth feeding, and reliable accuracy directly from the box.

This cartridge features Hornady’s advanced 175‑grain Sub‑X bullet, a monolithic copper-alloy design featuring an elastomer Flex Tip and bonded jacket-to-core construction. The Sub‑X bullet is engineered to achieve controlled expansion at subsonic velocities, retaining nearly 100 percent of its mass upon impact. The monolithic structure ensures consistent penetration and deep wound channels—ideal for ethical harvesting of whitetail deer, hogs, and other medium-game species in thick brush or quiet stalking scenarios.

When fired from a 20-inch barrel, the .30-30 Winchester 175gr Sub‑X Subsonic cartridge achieves a muzzle velocity of approximately 1,050 feet per second, producing 425 foot‑pounds of energy. At 150 yards, the bullet retains enough energy to expand reliably and deliver terminal effects comparable to classic .30-30 loads, while remaining subsonic and suppressor-friendly. This round delivers minimal muzzle blast and flash, making it well-suited for early-season deer hunts or low-light situations where stealth is critical.

Hornady loads this cartridge with temperature-stable, clean-burning propellant to reduce muzzle flash, suppress fouling, and maintain consistent shot-to-shot performance. The combination of tight brass tolerances, matched primers, and carefully regulated crimping ensures dependable feeding and ignition—even at reduced velocity. Hunters can expect reliable cycling in lever guns such as Marlins and Winchesters, as well as repeater-style bolt actions designed for subsonic use.

Designed for silence-sensitive applications, the Sub‑X bullet’s Flex Tip reduces recoil and barrel wear while optimizing ballistic performance of this subsonic 175gr load. Its controlled expansion at lower speeds maintains ethical terminal performance, providing deep penetration and energy transfer without overpenetration—key attributes for responsible hunting in densely timbered areas or hunt camps.

The Hornady 30-30 Win 175gr Sub‑X Subsonic presents a stealthy and effective factory load for hunters who require quiet terminal performance without sacrificing ethical results. Whether stalking deer in thick cover, hunting near camps, or using suppressors to minimize disturbance, this cartridge delivers steady accuracy, suppressed operation, and dependable stopping effectiveness—a modern subsonic solution in the classic .30-30 Winchester platform.
