Hornady 8mm .323 150gr InterLock SP Component Bullets
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 fit in the cartridge case.

Boris Mackenzie –
Used this bullet in a handloaded 8mm rifle for fallow deer hunting. The expansion was consistent and the bullet penetrated deeply without fragmenting. Good for medium-sized game in the field.
Christian McDonald –
Felt reliable in my 8mm setup. The InterLock design gave a solid expansion and the bullet held together well. Slightly heavier than expected, but the performance matched expectations.
Joan Gray –
Excellent for handloading. The secant ogive profile made the trajectory flatter than I expected. Shot several times in practice and the expansion was predictable and effective.
