Product DescriptionHornady InterLock Boat Tail Spire Point (BTSP) bullets are built for dependable terminal performance and accuracy on medium to large game. The InterLock design uses a raised ring inside the jacket that is embedded into the bullets core to help keep the core and jacket locked together during expansion for improved weight retention and energy transfer. A precisely tapered jacket is engineered to expand across a broad velocity range, while the cannelure supports consistent crimping and works with the InterLock ring to help prevent core-jacket separation. This .270 caliber/.277 diameter, 140-grain BTSP projectile features an aerodynamic profile intended to support stability, flatter trajectories, and accuracy.Product HighlightsInterLock ring mechanically locks jacket and core together for reliable expansion and weight retentionBoat tail spire point profile promotes lower drag, stability, and accurate long-range flightTapered jacket design helps deliver controlled expansion at both lower and higher velocitiesCannelure supports consistent crimping and helps maintain core-to-jacket integrity during expansionBulk-friendly packaging: 100 bullets per box (25 boxes per case)SpecsBrand: HornadyProduct Line: InterLockCaliber: .270Bullet Diameter: .277Bullet Weight: 140 grainBullet Type: Boat Tail Spire Point (BTSP)Construction: Jacketed lead, cup-and-core with InterLock ringFeatures: Cannelure; tapered jacket for controlled expansionQuantity: 100 bullets per boxCase Pack: 25 boxes per caseManufacturer Part Number: 2735UPC: 090255227352Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
