The Varmint Grenade has rapidly become one of the most popular varmint bullets. Based on a design Barnes developed for military applications, the hollow cavity, flat-base bullet features a copper-tin composite core surrounded by a guilding metal jacket. The Bullet remains intact at ultra-high velocities, while its highly frangible core fragments explosively on impact. Expending its energy early, the Varmint Grenade seldom exits large predators, leaving the pelts virtually undamaged. See an awesome video at our Barnes Bullets Home Page. *Flat Rate Bullets Only Shipping Terms: A USPS promotional FLAT CHARGE of $10 per shipment for bullets only orders.
