In the year 1866, more than 150 years ago, Oliver Winchester left a significant mark on the history of rifle-making when he founded the Winchester Repeating Arms Company with the intention of producing exceptional guns and ammunition. Oliver Winchester, “a man of vision and influence,” as many considered him, fulfilled his intention and built an industrial empire around the lever-action rifle. Sporting a polished brass receiver, the Model 1866 “Yellow Boy” lever-action rifle was the first gun to bear the Winchester name. Fast forward a few years, to 1880, Oliver Winchester died at age 70, but his legacy remained. The Winchester Model 1892 lever-action rifle soon proved itself to be the moviemaker’s favorite, while revolvers chambered in .38-40 Win., .44-40 Win. and .45 Colt were also well received.
Winchester helped pave the way for modern-day rifle manufacturers, and their decades of experience and craftsmanship can also be seen in their high-quality ammunition. They offer a variety of ammo for handguns, rifles, shotguns, and rimfire rifles. Today, the Winchester brand is owned by the Olin Corporation and made up of numerous members who are devoted to the maintenance, collecting, and learning about Winchester rifles and related products, as well as the role these products held in shaping the history of America’s firearms.
Winchester SXP, Super X Pump, is a pump-action shotgun first introduced in 2010 as a successor to the Winchester Model 1300 shotgun. The SXP’S action system uses four large rotary locking lugs that are located on the bolthead and lock into the receiver. What makes the SXP different from other shotguns is its special “inertia” bolt that provides the initial rearward movement of the slide. So, if the user fires the weapon one-handed without holding the forend it will often eject the fired shell by itself. It comes equipped with crossbolt safety and a drop-out trigger group that can be easily removed for cleaning, inspection, and lubrication. Its receiver is made of aluminum and the magazine has a 4- or 5-round capacity depending on the length of the shells used.
