Product DescriptionHornady InterLock bullets are designed to deliver reliable expansion and strong weight retention for hunting applications. The InterLock design uses a raised ring embedded in the bullet core to help keep the jacket and core locked together during expansion, helping preserve mass and energy on impact. A precisely controlled, tapered jacket supports consistent performance across a wide range of velocities, while the cannelure helps provide consistent crimping for handloaders. This 0.257-inch diameter, 117-grain Boat Tail Spire Point (BTSP) projectile is supplied as 100 bullets per box for reloading (not loaded ammunition).Product Highlights InterLock ring mechanically helps lock jacket and core together for improved weight retention during expansion 117 grain Boat Tail Spire Point profile supports accuracy, flatter trajectories, and hunting performance Tapered jacket engineered for controlled expansion across a wide range of impact velocities Cannelure aids consistent crimping and complements the InterLock design during expansion 100-count box of .25 caliber (0.257 in) jacketed lead reloading bullets (projectiles only)Specs Brand: Hornady Product Line: InterLock Bullet Type: Boat Tail Spire Point (BTSP) Caliber: .25 Cal Diameter: 0.257 in Bullet Weight: 117 gr Material: Jacketed Lead Ballistic Coefficient: 0.391 Sectional Density: 0.253 Quantity: 100 bullets per box Manufacturer Part Number: 2552 UPC: 090255225525Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
