Hornady 405 Cal 300gr InterLock SP

The Hornady 405 Cal 300gr InterLock SP is a high-performance bullet component crafted for handloaders and hunting enthusiasts who demand controlled expansion, deep penetration, and consistent accuracy in .405-caliber rifles. Weighing 300 gr with a .411-inch diameter, this 405 Cal 300gr InterLock SP features Hornady’s InterLock® core-to-jacket bonding system, delivering over 90% weight retention upon impact and dependable terminal results on large and dangerous game.

Designed with a spire-point profile, polymer tip, and boat-tail base, the 405 Cal 300gr InterLock SP achieves a high ballistic coefficient and flat trajectory when loaded between 2,300 and 2,500 fps. Common in classic cartridges like the .405 Winchester and .400 Jeffery, the 405 Cal 300gr InterLock SP offers hunters both energy retention and wind resistance at shot ranges of 200 to 400 yards.

The bonded-core construction in the 405 Cal 300gr InterLock SP mechanically locks the lead core to the copper jacket using Hornady’s InterLock® ring. This design prevents jacket-core separation on impact and ensures deep, straight-line penetration through heavy muscle, dense bone, and thick hide. Field reports confirm the 405 Cal 300gr InterLock SP creates large wound channels with ethical terminal performance.

Stabilizing efficiently in barrels with twist rates from 1:12 to 1:14, the 405 Cal 300gr InterLock SP feeds reliably in bolt-action, single-shot, and magazine rifles. Its concentric jacket, polished ogive, and smooth bearing surface support accurate seating, predictable point-of-impact, and dependable cycling. Reloaders trust the 405 Cal 300gr InterLock SP for consistent accuracy and performance across varying powder loads.

Manufactured at Hornady’s Grand Island, Nebraska facility, the Hornady 405 Cal 300gr InterLock SP is sold as a bullet component only and requires compatible brass, powder, and primers. With stringent quality control over tip alignment, jacket concentricity, and weight uniformity, the 405 Cal 300gr InterLock SP stands as a premier bonded-core bullet choice for hunters seeking reliable, accurate, and ethical performance in .405-caliber hunting rifles.
