Description
Hornady’s InterLock® SP bullet combines time-tested performance with modern design – the exposed lead tip ensures consistent expansion, while the InterLock® ring locks the core and jacket together for excellent weight retention and deep penetration. Ideal for deer-sized game, it gives you reliable knock-down power shot after shot.
-
Reliable Expansion & Terminal Performance
-
The bullet has an exposed lead tip, which promotes controlled expansion on impact and delivers hard-hitting terminal performance.
-
Thanks to its one-piece core, the bullet retains more mass and energy upon impact, leading to deeper penetration and consistent wound channels.
-
-
InterLock® Ring Technology
-
A raised InterLock® ring is embedded inside the jacket and into the core. This mechanically locks the jacket and core together during expansion, reducing the risk of separation and maximizing weight retention.
-
This results in reliable energy transfer and more effective terminal performance.
-
-
Optimized Jacket Design
-
The jacket has a tapered thickness that’s precisely engineered to promote consistent expansion across various impact velocities.
-
Inner grooves in the jacket help initiate controlled expansion even at longer ranges.
-
A cannelure works with the InterLock® ring to help ensure consistent crimping and maintain the integrity of the bullet on impact.
-
-
Ballistic Efficiency
-
Uses a secant ogive shape, providing better aerodynamic efficiency, improved stability in flight, and flatter trajectories.
-
Example spec (30-06, 150 gr SP): 0.338 G1 ballistic coefficient.
-
-
Premium Components
-
Loaded with high-quality powder matched to each caliber for consistent velocity and pressure — compatible with semi-automatic rifles.
-
Uses top-tier brass cases and primers for reliable ignition and consistent performance.
-
-
Proven Performance for Game
-
Specifically designed for medium to large game – (UK Deer species).
-
-
Durability & Weight Retention
-
The combination of one-piece core + InterLock® ring allows the bullet to retain more of its weight on impact, improving penetration and energy transfer.
-
Even at high velocities, the design helps maintain structural integrity.
