These all-new bullets from Barnes Bullets feature Multi-Purpose Green (MPG) technology developed for military and law enforcement applications. MPG bullets feature a highly frangible, powdered-metal copper-tin core inside a guilding metal jacket. These Multi-Purpose Green bullets are exceptionally accurate. They're ideal for shooting steel targets, competition, plinking, varmint hunting and home defense. "Green" is military shorthand for "lead-free," a requirement in military and LE practice environments. 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. .22, 55 grain. Box of 100 rounds.
