The Barnes Bullets XPB Pistol in 460 S&W Mag is a purpose-built handgun bullet for hunters and sport shooters who demand reliable expansion and deep, consistent penetration. Built entirely from copper with no lead core, the XPB delivers energy transfer that outperforms traditional jacketed lead-core designs while producing virtually no airborne lead residue—a real benefit for frequent shooters at indoor ranges or during extended practice sessions.
Each box contains 20 rounds of .451-diameter, 275-grain XPB projectiles engineered for the 460 S&W Magnum cartridge. The all-copper construction inherent to XPB technology creates multiple petals upon impact, expanding reliably across a wide range of velocities. Weight retention is exceptional, meaning the bullet stays together through bone and heavy muscle rather than fragmenting or shedding mass—critical for hunting larger game or defensive scenarios where penetration matters.
Reloaders and handloaders favor XPB bullets for their consistency and accuracy. The solid copper design eliminates the jacket-separation problems that plague some conventional bullets, and the uniform construction makes them predictable under varying hunting conditions. Whether you're loading for hunting hog, elk, or large-frame defensive work with the 460 S&W Mag, the XPB's proven expansion and penetration characteristics earn it a spot in serious handgun ammunition.
These are component bullets for reloading—not loaded ammunition. Prepare your brass, powder, and primer separately, or use them with a qualified reloading service.

Frequently Asked Questions
What is the XPB bullet technology?
XPB (X-Bullet Pistol) is Barnes' proprietary all-copper bullet design. It expands on impact by splitting into multiple petals while the core remains intact, delivering controlled expansion and deep penetration. Because there's no lead core or jacket to separate, the bullet performs consistently across a range of velocities.
Are these finished ammunition or reloading components?
These are reloading components—bullets only. You will need to supply your own brass, powder, and primers to assemble loaded ammunition.
What is the 460 S&W Magnum, and what firearms use it?
The 460 S&W Magnum is a powerful revolver cartridge designed for large-bore revolvers. We don't have a list of specific firearms compatible with this load, but 460 S&W Mag is a specialized cartridge; verify your firearm's markings and consult the manufacturer to ensure compatibility before loading.
Why choose lead-free bullets for pistol shooting?
Lead-free bullets like the XPB eliminate airborne lead exposure during shooting, which is especially valuable in indoor ranges or during extended practice. They're also compliant in regions with lead-ammunition restrictions.
