After much anticipation, Winchester Varmint X now includes Shot-Lok Technology in a new shotshell load developed specifically for hunting predators. The popularity of Shot-Lok Technology in other Winchester products such as Long Beard XR and Rooster XR rolled seamlessly into what is now one of the most devastating shotshell products available for long range shots on coyotes, foxes and more.Shot-Lok Technology includes a liquid gel that surrounds the pellets in the shot cup and then hardens. The shot then launches from the barrel nearly perfectly round for extremely tight, long-range patterns. The new Varmint-X shotshell load is available in 3-inch, 1½-ounce plated BBs traveling at 1,300 feet per second (fps). At 40 yards, expect more than 12 inches of penetration along with devastating knockdown power.
