The Hornady .321 32 Cal 170 Grain FP InterLock bullet is an inert handloading component projectile designed specifically for the .32 Winchester Special cartridge. Featuring a blunt Flat Point profile with an exposed lead tip, this projectile is engineered for safe cycling within tubular magazine lever-action rifles. It incorporates Hornady's InterLock technology, which uses an internal mechanical ring to lock the one-piece lead core to the jacket during expansion, preserving bullet mass and kinetic energy upon impact.

Key Features

• Tubular Magazine Compatibility: Built with a Flat Point profile that prevents primer detonation against adjacent cartridges under recoil in tubular magazines.
• InterLock Retaining Ring: Features a raised internal jacket ring mechanically embedded into the lead core to prevent core-jacket separation during expansion.
• Controlled Terminal Performance: Features inner jacket grooves and a tapered jacket construction designed to initiate reliable upset across diverse impact velocities while preventing jacket fragmentation.
• Integrated Cannelure: Features a dedicated crimping groove that facilitates a secure mechanical roll crimp, preventing bullet movement during recoil and magazine feeding.

Who is the Hornady .321 32 Cal 170 Grain FP InterLock bullet for?

• Handloaders loading for .32 Winchester Special lever-action rifles — Sized to a precise 0.321 inches bullet diameter with an integrated crimping cannelure, providing this specific category of handloading rifle bullet with safe feeding and recoil stability in tubular magazine firearms.
• Hunters pursuing medium game in timber or close cover — Features a heavy 170 grains bullet weight and InterLock core-jacket retention design, delivering deep penetration and controlled expansion on medium game weighing between 50 to 300 lbs at typical woodland hunting distances.

Less suitable for: Long-range shooting beyond 150 to 200 yards, where the low 0.249 G1 ballistic coefficient and flat point nose shed velocity rapidly; long-range hunters require pointed aerodynamic spitzer or boat-tail rifle bullets loaded for box-magazine rifles. It is also unsuitable for standard 8mm Mauser chambers requiring larger .323" diameter projectiles.
