Hornady 303 Cal 174gr InterLock RN (Bulk / OEM)

Hornady 303 Cal 174gr InterLock RN

The Hornady 303 Cal 174gr InterLock^® RN (Round Nose) bullet is a classic heavy-hitting option designed for vintage military rifles, big game hunting, and reloaders who favor traditional bullet profiles. This projectile is a perfect match for the .303 British cartridge and similar calibers, offering controlled expansion, deep penetration, and excellent weight retention. With a round nose profile that enhances terminal performance at moderate velocities, it excels in brush hunting or shots taken inside 200 yards.

Like all of Hornady’s InterLock^® bullets, the 174gr RN model features an exposed lead tip for immediate expansion upon impact. The core and jacket are mechanically locked together using Hornady’s patented InterLock^® ring—a raised inner ring embedded in the lead core—which ensures the two components stay bonded during expansion. This prevents fragmentation and allows for deeper wound channels, even when the bullet encounters thick muscle or bone.

Designed with a secant ogive for better in-flight stability and accuracy, this round nose bullet offers a balance between vintage appeal and modern ballistic consistency. The internal grooves in the jacket are engineered to direct the expansion process and maintain bullet shape as it passes through the target. The cannelure allows for consistent and secure case crimping, helping to prevent bullet setback and maintain performance over repeated chamberings.

The Hornady 303 Cal 174gr InterLock RN is also available in bulk bullets packaging, making it a cost-effective solution for high-volume reloaders working with surplus rifles or planning extended hunting seasons. Its heavy weight and time-proven round nose design make it a reliable performer for hunting deer, hogs, and similar game where classic performance is still king.

INNER GROOVES

Strategically weaken the upper section of the jacket, ensuring consistent, controlled expansion, even at long range.

TAPERED JACKET

Jacket thickness is precisely controlled for expansion at all velocities.

ONE-PIECE CORE

Does not separate like two-piece divided cores. The InterLock^® retains more mass and energy for deep penetration and large, consistent wound channels that ensure quick, clean kills.

CANNELURE

Provides accurate and consistent crimping and works with the InterLock^® ring to ensure the core and jacket remain locked during expansion.

INTERLOCK^® RING

The raised InterLock^® ring is embedded in the bullet’s core, ensuring the core and jacket are locked in one piece during expansion to retain mass and energy.
