Starline 450 Bushmaster Brass

Starline 450 Bushmaster Brass

Starline 450 Bushmaster bulk brass starts with consistent metallurgy, precise tooling, tight quality control, and 30-plus years of experience. Every piece is guaranteed to have flash hole presence and be of the correct length and diameter. Unlike some competitors, Starline’s vertically drawn process effectively minimizes wall thickness variation, delivering consistent performance and long service life for reloaders.

The .450 Bushmaster was developed as a hard-hitting, straight-wall cartridge optimized for close-range hunting—particularly in states that permit straight-wall calibers for whitetail and other medium-to-large game. Initially tailored for the AR-15 platform, it requires only a dedicated upper to convert from standard 5.56/.223 setups, making it a practical and powerful upgrade.

With the growing popularity of this round, many bolt-action options have entered the market as well. Ruger offers models like the American Ranch and Gunsite Scout rifles chambered in .450 Bushmaster, adding to the cartridge’s versatility. Starline brass accommodates the common .452″ diameter projectile, and reloaders can take advantage of bullet weights ranging from 160 to over 350 grains to suit everything from target practice to big game hunting.

Whether you’re hunting in thick brush or preparing for a cold-weather range session, Starline 450 Bushmaster brass delivers the precision and strength you need. Its robust construction and heat-treated durability make it a trusted choice for reloaders seeking optimal case life and reliability.
