About InterLock Ammunition

These loadings feature Hornady's proven hunting bullets designed with a mechanical locking system that prevents jacket separation during expansion. Developed by Hornady for hunting applications, the Interlock bullet incorporates a unique ring system that mechanically locks the jacket and core together, ensuring controlled expansion and maximum weight retention upon impact with game. The InterLock design provides reliable terminal performance and deep penetration while maintaining the expansion characteristics necessary for effective energy transfer on medium to large game animals. These types of loadings are well-suited for big game hunting applications where reliable expansion, maximum weight retention, and proven terminal performance are essential for ethical harvesting of game animals at typical hunting distances.

Common InterLock Calibers

• 6.5 Creedmoor:The 6.5 Creedmoor was introduced by Hornady in 2007 and serves as a modern expansion on the concept of a 6mm round. This relatively new cartridge has become increasingly popular in recent years, establishing a solid reputation in both the world of hunting and precision shooting. Like the .243 Win, the 6.5 Creedmoor is also well-known for its light recoil, accuracy, and flat trajectory. The cartridge has garnered attention from law enforcement and military agencies as rifles in the caliber have been tested and employed in marksman and sniper type roles.
• .270 Winchester:The .270 Winchester cartridge was developed by Winchester Repeating Arms Company in 1923 and released to the public in 1925. It was designed to be a flat-shooting cartridge suitable for long-range shooting and big game hunting. Its parent case is the .30-06 Springfield and notably features a tamer recoil impulse and smaller diameter projectile. The .270 Winchester quickly gained popularity among hunters and shooters due to its versatility and effectiveness on a wide range of game.
• .30-30 Winchester:The .30-30 Winchester, also known as the .30 Winchester Center Fire (WCF), is a popular rifle cartridge introduced in 1895 for the Winchester Model 1894 lever-action rifle. It is one of the first cartridges designed for smokeless powder, offering a significant improvement in ballistics over black powder cartridges of the time. The .30-30 has become a staple in American deer hunting, known for its moderate recoil, accuracy, and effectiveness at typical hunting ranges.
• .308 Winchester:The .308 Winchester is an American cartridge that was introduced in 1952. The cartridge served as the basis for the 7.62x51mm NATO cartridge, a long-standing military cartridge utilized by many countries. The .308 Winchester itself is derived from the .300 Savage and was designed with the intent of matching ballistic performance similar to the .30-06 Springfield in a smaller package. Many firearms have been chambered in the .308 Winchester cartridge. A wide variety of commercial firearms have been chambered in the .308 Winchester, typically in semi-automatic or bolt action form. While newer cartridges have been introduced which surpass the .308 Winchester in certain use cases, the cartridge still remains popular among shooters. The cartridge is an incredibly versatile cartridge which can easily be pressed into a variety of roles.
• .30-06 Springfield:Like the name suggests, the .30-06 Springfield was developed by Springfield Armory. The cartridge made its debut in 1906 and was adopted by the military that same year. The “06” in the name actually refers to 1906, the year of the cartridge’s introduction. The round was borne from a desire to replace the .30-40 Krag cartridge which was being eclipsed by other service rifles at the time. Unlike spitzer-tipped (pointed projectile) cartridges such as the .303 British and 8mm Mauser, the .30-40 Krag featured a round-nosed projectile. The cartridge has been utilized in rifles and machine guns in conflicts across the globe since its inception. Beyond use in armed conflicts, the cartridge has been enjoyed by hunters and target shooters. The cartridge has been utilized by hunters across the globe throughout history. Notably, President Theodore Roosevelt used a .30-06 Springfield chambered rifle on safari in Africa. At the end of the day, the cartridge is a round which has been proven in both combat and in the field that continues to be popular today.
