MPG bullets from Barnes feature a highly frangible, powdered-metal copper-tin core inside a guilding metal jacket.
Unlike frangible bullets lacking a protective jacket, MPG bullets remain intact under the rigors of handling, feeding and firing. This eliminates the primary cause of jammed actions and plugged barrels often experienced when firing frangible ammunition.
These open-tip bullets remain intact at ultra-high velocities and extreme rates of spin. On impact, they deliver explosive fragmentation.
