Hornady 3210 InterLock .321 Caliber 170 Grain Flat Point Reloading Bullets, 100 Count

Hornady 3210 InterLock reloading bullets are designed for dependable performance and controlled expansion in compatible .321 caliber cartridges. Each 170-grain flat point bullet features Hornady’s InterLock design, which uses a raised ring inside the jacket that is embedded into the lead core. This construction helps keep the core and jacket together during expansion, supporting consistent weight retention and energy transfer.
The tapered copper jacket is precisely controlled to promote reliable expansion across a broad range of velocities. The one-piece lead core is designed to resist separation from the jacket, while the integrated cannelure provides a secure, consistent crimp during the handloading process. Working together with the InterLock ring, the cannelure helps maintain the connection between the core and jacket during bullet expansion.
With a .249 ballistic coefficient and .236 sectional density, these Hornady bullets are suited for reloaders seeking repeatable component specifications and consistent cartridge assembly. The flat point profile is a practical choice for compatible rifles and loads that call for this bullet style. Each box contains 100 copper-jacketed, lead-core reloading bullets. Always consult a current Hornady reloading manual and verify cartridge, firearm, seating, and load data compatibility before use.
