Buffalo Bore's Premium Supercharged ammo is a powerful rifle ammunition manufactured with exacting standards with the gun owner in mind. This Super Charged load is designed to be a premier load providing devastating, one shot terminal destruction of Big Game. When the Spitzer bullets are traveling the bullet will mushroom violently and 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.
