Special Features

• InterLock ring is a raised band embedded directly into the bullet core, mechanically locking the jacket and core together throughout expansion to retain mass, momentum, and energy for deep penetration on medium and large game.
• One-piece lead core delivers uniform density and mass distribution that produces consistent expansion and straight-line wound channels, eliminating the inconsistencies of two-piece divided core designs.
• Strategically placed interior grooves weaken the upper jacket section in a controlled pattern, ensuring repeatable expansion across the full velocity range from close range to extended field distances.
• Precisely tapered jacket controls expansion at high velocity while promoting reliable upset at lower impact velocities, making this bullet dependable across the full family of 30 caliber hunting platforms.
• Secant ogive spire point profile delivers lower drag, improved stability, flatter trajectories, and greater accuracy compared to traditional round nose hunting bullet designs.
• Cannelure provides a firm crimp location and works in tandem with the InterLock ring to further secure core-jacket integrity throughout the terminal phase.

Practical Benefits
