The Hornady InterLock 7mm 139 grain spire point bullet is a workhorse for reloaders building big game hunting ammunition. Built around Hornady's proven InterLock ring system, these bullets lock the core and jacket together during expansion to help maintain velocity and energy through heavy bone and thick hide. The one-piece core-and-jacket construction combined with a polymer tip keeps the bullet nose-on-target while delivering the weight retention serious hunters demand for consistent, ethical kills.
Whether you're handloading for a 7mm Remington Magnum, 7x57, or similar 284-caliber cartridge, these spire points deliver a clean ballistic profile and the controlled expansion that separates field-tested ammunition from guesses. A box of 100 gives you the volume you need for load development, practice, and season prep without running out mid-project.
Hornady InterLock bullets have earned their reputation in the field. Reloaders value the consistent construction and the engineering that helps bullets perform when it counts—when you're facing an elk at 200 yards or a whitetail across a canyon. These are bullets built to finish the job.
