Barnes Bullets
Barnes Triple-Shock X (TSX) 450 Bushmaster 275 grain bullets are engineered for hunters who demand reliable, lead-free performance in big-bore rifle applications. Built from 100% copper, these hollow point projectiles are constructed to retain their full weight through bone and tissue, translating to deep, consistent penetration on game—exactly what you need when you're hunting with a 450 Bushmaster's raw power.
The TSX design incorporates precisely positioned grooves cut into the bullet's body. These rings serve a dual purpose: they manage firing pressure and reduce copper fouling, which means you can push velocities higher while keeping your barrel cleaner between shots. For hunters chasing lead-free ammunition, that's a significant practical advantage on extended range days.
Each box contains 20 rounds of flat-base ammunition ready for reloading or loaded-round applications. The combination of the 275-grain mass, lead-free construction, and TSX expansion geometry makes this a solid choice for medium to large game where penetration and weight retention are non-negotiable.

| Bullet Weight | 275 grains |
| Bullet Type | Lead-Free Hollow Point |

The grooves cut into the TSX bullet's body relieve firing pressure, allowing safe loading to higher velocities while reducing copper fouling in your barrel. This helps keep your rifle cleaner and extends time between cleaning cycles.
Yes. Barnes TSX bullets are constructed from 100% copper and contain no lead, making them compliant with lead-free ammunition requirements in many jurisdictions.
The TSX is designed to retain 100% of its original weight even after passing through dense tissue and bone, delivering the deep penetration that 450 Bushmaster hunters rely on.
These are flat-base bullets, which provide reliable feeding and consistent seating in your reloading dies or loaded ammunition—a straightforward design that works well in most 450 Bushmaster rifles.
