The Hornady Custom 405 Winchester 300 grain InterLock Spire Point ammunition is purpose-built for hunters and shooters who favor the .405 Winchester cartridge. This 20-round box delivers the controlled expansion and deep penetration you need for big-game hunting with a projectile engineered to hold together through heavy bone and muscle. The InterLock design—a mechanical locking ring that binds core to jacket—resists core separation and ensures consistent terminal performance downrange.
The spire point bullet profile balances aerodynamic efficiency with the hunting performance the .405 Winchester was designed for. Hornady's reputation for meticulous ammunition assembly means you get consistent chamber fit, reliable ignition, and the velocity stability that translates to clean, ethical kills at reasonable hunting distances. Whether you're working a lever-action rifle or a modern single-shot, this ammunition respects the heritage and practical accuracy of one of America's classic cartridges.
Each box contains 20 rounds, making it an economical way to stock up for the season or test your rifle's preferred load. Hornady Custom ammunition is a solid middle ground between budget practice rounds and premium match-grade offerings—good enough for serious hunting, straightforward to shoot, and available when you need it.
