HORN 4503 BULL .458 350 FP INTERLOCK 50/15

Built for hunters and handloaders seeking dependable performance, the Hornady 4503 InterLock .458-inch, 350-grain Flat Point bullet combines a proven design with controlled expansion and strong weight retention. Its flat-point profile and substantial 350-grain construction make this 45-caliber bullet a practical choice for suitable loads calling for a flat-point projectile. Each box contains 50 bullets, and each case includes 15 boxes for convenient reloading inventory.

At the heart of Hornady’s InterLock design is a raised internal ring embedded in the bullet’s core. During expansion, this ring helps keep the core and jacket mechanically locked together, supporting retained mass and energy. A precisely tapered jacket is engineered to promote expansion across a range of velocities, while the one-piece core is designed to resist separation. The cannelure supports accurate, consistent crimping and works with the InterLock ring to help maintain bullet integrity.
