Hornady 4503 InterLock .458-Caliber 350 Grain Flat Point Reloading Bullets, 50 Count

Hornady 4503 InterLock reloading bullets are designed for dependable performance in .45-caliber applications requiring a .458-inch bullet diameter and 350-grain flat point profile. Each bullet uses Hornady’s InterLock design, featuring 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 has precisely controlled thickness to promote reliable expansion across a broad range of velocities. A one-piece lead core helps prevent core separation, while the cannelure supports accurate, consistent crimping during the reloading process. The cannelure also works with the InterLock ring to help maintain the connection between the core and jacket during expansion. These features make the Hornady 4503 a practical choice for reloaders seeking a flat point bullet with controlled construction and repeatable performance.
Each box contains 50 copper-jacketed, lead-core bullets with a lead tip, a .195 coefficient, and a .238 sectional density. These components are intended for use in properly developed handloads and should be matched with appropriate loading data, equipment, and procedures. As reloading bullets, they are supplied as components rather than loaded ammunition. Hornady’s established manufacturing standards provide reloaders with a consistent projectile option for applications where bullet construction, crimping performance, and dependable expansion characteristics are important.
