Buffalo Bore's Premium Supercharged ammo is powerful rifle ammunition manufactured with exacting standards with the gun owner in mind. Buffalo Bore produces strictly big bore ammo with massive firepower and dramatic results. These Super Charged loads were designed to be premier loads providing devastating, one shot terminal destruction of Big Game. When the Spitzer bullets are traveling these velocities the bullet will mushroom violently. It may even fragment, depending on bullet placement, caliber and impact speed. For big game up to 350 lbs, tremendous penetration is not needed, so this bullet mushrooms radically and might even break up. When high speed bullets act this way terminally, the effect is devastating and they absolutely dump deer sized game animals in their tracks.
