Reliable Expansion and Deep Penetration
The Hornady .312 InterLock RN bullet features an exposed lead tip for controlled expansion and strong terminal performance. Its signature round nose design, combined with the proven InterLock® ring, ensures deep penetration and excellent energy retention. The secant ogive profile is one of the most efficient ballistic shapes, providing stable flight behavior even at medium ranges. The mechanical bonding of jacket and core keeps them locked together during expansion.
Internal Grooves
Strategically weakened upper jacket section promotes uniform, controlled expansion—even at longer ranges.
Tapered Jacket
Precisely controlled jacket thickness ensures consistent expansion across a wide velocity range.
One-Piece Core
Unlike dual-core bullets, the InterLock retains its mass and energy for deep penetration and large, uniform wound channels for rapid, humane knockdown.
Cannelure
Enables secure and consistent crimping. Combined with the InterLock ring, it helps keep the core and jacket firmly together during expansion.
InterLock® Ring
This raised ring is embedded in the bullet’s core to lock the core and jacket together, preserving mass and energy throughout expansion.
