Hornady 8mm 170gr InterLock RN

The Hornady 8mm 170gr InterLock RN is a robust bullet component designed for handloaders seeking controlled expansion, deep penetration, and reliable feeding in classic .323-caliber rifles. Weighing 170 gr with a .323-inch diameter, the 8mm 170gr InterLock RN features Hornady’s InterLock® core-locking ring, which mechanically bonds the lead core to the jacket—ensuring over 90% weight retention and dependable terminal performance in rifles like the 8mm Mauser and .325 WSM.

The 8mm 170gr InterLock RN employs a round-nose profile tailored for smooth chambering and consistent ignition in bolt-action, lever-action, and single-shot platforms. This simple geometry, combined with a uniform bearing surface and concentric jacket, provides the 8mm 170gr InterLock RN with steady alignment, minimized barrel fouling, and reliable cycling. Handloaders appreciate its easy seating and consistent accuracy across varied magazines and rifle types.

Inside the 8mm 170gr InterLock RN, the bonded-core design resists jacket-core separation upon impact, allowing deep penetration into heavy muscle and bone. Field-testing and hunter reports confirm that the 8mm 170gr InterLock RN produces clean wound channels and retains mass when used on medium and large game. Even at typical velocities of 2,500–2,700 fps, this bullet maintains structural integrity throughout performance.

The weight and geometry of the 8mm 170gr InterLock RN stabilize easily in barrels with twist rates between 1:10 and 1:12, making it suitable for diverse rifles and hunting conditions. Consistent ogive alignment and bearing surface quality support tight groupings up to 300 yards. Reloaders trust the 8mm 170gr InterLock RN for its uniform point-of-impact and reliable cycling across multiple load configurations.

Manufactured in Hornady’s Grand Island, Nebraska facility, the 8mm 170gr InterLock RN is sold as a bullet component only and must be handloaded with compatible brass, powder, and primers. With strict quality control over tip form, jacket concentricity, and core bonding, the 8mm 170gr InterLock RN emerges as a trusted choice for hunters aiming for bonded-core durability, deep penetration, and field reliability in .323-caliber bullet applications.
