Hornady 25 Cal .257 117 gr InterLock® BTSP

Our traditional line of bullets feature exposed lead tips for controlled expansion and hard hitting terminal performance. Most have our pioneering secant ogive design-one of the most ballistically efficient profiles ever developed. Most feature our exclusive InterLock® design--a raised ring inside the jacket that is embedded in the bullet's core that keeps the core and jacket locked together during expansion to retain mass and energy.

SECANT OGIVE DESIGN

Pioneered by Hornady® for use in hunting bullets, this technology broke new ground in ballistic engineering and is now used in bullets for everything from match to varmint shooting.

The secant ogive is a geometrically developed design that creates the most ballistically efficient profile, yet retains the optimum bearing surface. The combination of the slender point and increased bearing surface results in lower drag, increased stability, flatter trajectories, and amazing accuracy.

Features:

1. Inner Grooves
   Strategically weaken the upper section of the jacket, ensuring consistent, controlled expansion, even at long range.
2. Tapered Jacket
   Jacket thickness is precisely controlled for expansion at all velocities.
3. One-Piece Core
   Does not separate like divided cores. The InterLock® retains more mass and energy for deep penetration and large, consistent wound channels that ensure quick, clean kills.
4. Cannelure
   Provides accurate and consistent crimping and also works with InterLock® ring to ensure the core and jacket remain locked during expansion.
5. 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.
