Building solid ammunition for your 450 Bushmaster AR platform means starting with the right bullet, and Hornady InterLock 450 Bushmaster 245 grain spire point bullets deliver the controlled expansion and mass retention that serious hunters rely on. Whether you're handloading for whitetail, hog, or other medium to large game, these bullets are engineered to perform consistently across the velocity ranges you'll realistically see from a modern intermediate cartridge. The 245-grain spire point profile offers a balance between ballistic efficiency and the stopping power that makes the 450 Bushmaster a legitimate hunting round.

At the core of Hornady's InterLock design is a simple but effective principle: keep the jacket and core working as one unit during expansion. The raised InterLock ring embeds itself into the bullet's lead core, preventing separation when the bullet expands in tissue. That means better retained mass, deeper penetration, and more reliable wound channels—the kind of terminal performance that translates to cleaner, faster kills and less tracking. Paired with inner grooves that weaken the jacket strategically and a tapered jacket engineered for controlled expansion at all practical velocities, you get expansion that's consistent whether you're at 50 yards or pushing distance.

The cannelure does double duty: it gives you a crimp groove for secure seating in your 450 Bushmaster cases, and it works with the InterLock ring to lock everything together during impact. This one-piece core design means no two-piece separated cores losing energy—just reliable, deep-penetrating performance. Each box contains 50 bullets, so you can load a full hunting season's worth or work up test loads to dial in your load data. If you're serious about 450 Bushmaster reloading, Hornady InterLock is a proven platform used by hunters across North America.
