Hornady 8mm .323 150gr InterLock SP Component Bullets

• Hornady InterLock SP component bullet for handloaders — 8mm (.323"), 150 grains
• Exposed soft-point tip initiates controlled expansion at a wide range of impact velocities
• InterLock ring locks jacket and core together during expansion for high weight retention
• Secant ogive design reduces drag for flatter trajectories and improved long-range accuracy
• Tapered jacket provides consistent expansion at both high and reduced velocities
• Cannelure provides a consistent, accurate crimp seat during the loading process
• Sold as component projectiles — no case, primer or propellant included

The Hornady InterLock SP is a traditional hunting bullet designed to deliver controlled expansion and deep penetration on medium to large game. At 8mm (.323" diameter) and 150 grains, this soft-point projectile is well suited to handloaders building rounds for red deer, fallow, and similar quarry with an 8mm rifle. The exposed lead tip initiates reliable expansion on impact at a wide range of velocities, while the InterLock ring — a raised band moulded into the jacket and embedded in the lead core — locks the two together during expansion to retain mass and energy. The secant ogive profile, pioneered by Hornady, reduces drag and improves ballistic efficiency, resulting in flatter trajectories. A tapered jacket ensures consistent expansion across velocity ranges, and the cannelure provides a secure crimp seat during the loading process. These are component projectiles sold for handloading — no case, primer or propellant is included. No firearms certificate is required to purchase component bullet heads in the UK.
