Hornady InterLock .411 Caliber 300 Grain Spire Point Reloading Bullets, 50 Count - Part 41051

Hornady InterLock .411 caliber 300 grain Spire Point reloading bullets are designed for reliable performance during expansion while helping retain core and jacket integrity. Part number 41051 features Hornady’s InterLock design, which uses a raised ring inside the jacket and an embedded core to help keep the lead core and copper jacket locked together during expansion. This construction helps the bullet retain mass and energy through its intended performance range.
The tapered copper jacket has precisely controlled thickness to support consistent expansion at varying velocities. A one-piece lead core helps prevent core separation, while the cannelure provides accurate, consistent crimping during the reloading process. Working together with the InterLock ring, the cannelure helps maintain the connection between the core and jacket as the bullet expands. The Spire Point profile is suitable for reloaders seeking a streamlined, dependable bullet design for compatible .405 caliber applications.
Each bullet features a .411-inch diameter, a 300-grain weight, a lead tip, a lead core, and a copper jacket and coating. With a .250 coefficient and .254 sectional density, these bullets provide defined ballistic specifications for load development and ammunition planning. The 50-count package offers a practical quantity for reloading sessions, testing, and maintaining an organized supply of compatible components. Verify firearm, cartridge, and load data compatibility before use, and always follow established reloading practices and published data.
