Federal brought back the immensely popular Barnes Triple-Shock X. This proven all-copper hollow point groups tightly at long range and delivers consistent, large-diameter expansion. The monolithic design retains nearly 100 percent of its weight on impact to penetrate deep, and its grooved shank minimizes barrel fouling and improves accuracy.Specifications: Caliber 30-30 Winchester Bullet Type Barnes TSX Bullet Weight 150 GR Muzzle Energy 1641 ft lbs Muzzle Velocity 2220 fps Rounds Per Box 20 Boxes Per Case 10 Casing Material Brass
