For predator and varmint hunters working moderate to long range, the Winchester Super-X Varmint 22-250 Remington delivers a 55 grain jacketed hollow point at 3680 feet per second muzzle velocity and 1654 foot-pounds of energy. The 22-250 Remington is a centerfire rifle cartridge optimized for flat trajectories and minimal wind drift out to 300 yards, making it a staple for prairie dog, ground squirrel, and coyote control. This load pairs a thin alloy jacket with a polymer tip engineered for rapid expansion and explosive fragmentation on impact — you get maximum energy transfer and minimal exit-wound tracking required.
Built for the Box
Winchester chambers each round in reloadable brass with a non-corrosive boxer primer. The 55 grain bullet carries a G1 ballistic coefficient of 0.269, sufficient for supersonic flight and predictable drop compensation at typical varmint engagement distances. The polymer tip maintains bullet integrity during magazine cycling and initiates expansion within milliseconds of target contact. The thin jacket fragments readily, creating a wound channel that stops small to medium game without over-penetration. Each box holds twenty rounds, and shipping weight is 1.16 pounds per box.
