Barnes Multi-Purpose Green (MPG) 22 Cal 55 Grain Lead-Free Hollow Point Bullets - Box of 100

Barnes Multi-Purpose Green (MPG) lead-free rifle bullets deliver the accuracy and reliability modern shooters demand, whether you're running competition loads, drilling steel targets, or building defensive ammo. These 55-grain .224 projectiles combine a frangible powdered-metal copper-tin core with a protective gilding metal jacket—a design born from military and law enforcement requirements. The result is a bullet that fragments reliably on impact while staying intact through the feeding and firing cycle, eliminating the jams and barrel plugging that plague traditional frangible ammunition.

Built for semi-automatic rifles with 1:9" twist rates or faster—including AR-15, M4, and HK416 platforms—the MPG bullet handles extreme rotational speeds and ultra-high velocities without coming apart before impact. That combination of structural integrity in the magazine and explosive performance downrange makes these rounds equally at home punching steel, plinking, or filling a home-defense magazine. The "Green" designation is military shorthand for lead-free, a practical choice for indoor ranges, training environments, and shooters who want a cleaner shooting experience.

Reloaders and factory-ammo builders have long trusted Barnes for precision and consistency. The MPG line extends that reputation into lead-free territory without compromise—you get the same attention to concentricity and weight uniformity that keeps groups tight and barrel life long. At 55 grains, this bullet weight pairs naturally with common powders and primers, making it straightforward to develop loads that shoot accurately and perform as intended.

Frequently Asked Questions

Will these bullets work in my AR-15?

Yes. The 55-grain MPG is designed for AR-15 and similar semi-automatic rifles (.224 bore) with rifling twist rates of 1:9" or faster. Most modern AR-15s meet that specification; if you're unsure of your barrel twist, check your upper receiver markings or the manufacturer's data sheet.

What makes these bullets lead-free?

Barnes MPG bullets use a frangible core made from powdered metal (copper and tin) instead of lead. The core is surrounded by a gilding metal jacket, which keeps the bullet intact during handling and feeding while allowing it to fragment on impact. This makes them ideal for indoor ranges and facilities that restrict lead ammunition.

Can I use these for hunting or just target shooting?

While MPG bullets excel at steel-target shooting and competition use, they're also suitable for varmint hunting and home-defense applications where their rapid fragmentation is an asset. Always verify that lead-free ammunition complies with local hunting regulations in your area.

Why don't these bullets jam or plug my barrel like other frangible ammo?

The key difference is the protective gilding metal jacket. Many frangible bullets lack a jacket and crumble during feeding and firing, causing jams and fouling. Barnes MPG bullets keep their jacket intact throughout the firing process, then fragment reliably on impact. That structural robustness is what eliminates the reliability issues that plague uncoated frangible designs.
