Product Info for Winchester Super-X Rifle 8x57mm Mauser 170 grain Power-Point Centerfire Rifle Ammunition

The Winchester Super-X Power Point Centerfire Rifle Ammunition is a classic soft lead core bullet that provides rapid expansion and full functionality. This bullet was named after Winchester's famed "Super-X" because of the "X" that is featured on the new Long X. This new design of bullet features a "crosshatched" look on the nose that is typical of the X class bullets Winchester is famous for. The "X" also appears on the base of the bullet where the "X" and "X" cross slots are located. These feature notches on the jacket of the bullet where the "X" and "Y" crosshatches are located. This allows the "X" to "unfold" or "unfold" as the bullet expands - expanding laterally then spreading out to provide maximum expansion. This assures the "X" factor of double-diamond shaped petals that offer maximum expansion and a "X" type of effect on the target. This is due to the "X" type of notching on the bullets cross section or "X" type cross slotted or "X" shaped bullet. Also, a "Y" shaped jacket mouth or "X" type jacket, provides maximum expansion.image
