Winchester Super-X 220 Swift ammunition delivers the flat trajectory and explosive terminal performance that varmint hunters and precision shooters demand from America's fastest commercial cartridge. This 50-grain Jacketed Soft Point (JSP) load achieves a scorching 3870 fps muzzle velocity, generating 1663 ft-lbs of energy downrange—making it a formidable choice for long-range varmint work, predator control, and small-game hunting where speed and accuracy matter. Winchester's Super-X line combines rigorous quality control with field-proven reliability, giving you ammunition you can trust when conditions are demanding.
The 220 Swift has earned its reputation as an uncompromising cartridge for shooters who want to stretch their effective range and minimize wind drift. The 50-grain JSP bullet is light enough to take full advantage of the cartridge's inherent velocity while delivering reliable expansion on target. Whether you're working from a bench at 200 yards or hunting at extended distances, this ammunition's consistent performance and tight manufacturing tolerances mean you'll spend less time chasing fliers and more time making clean, ethical shots.
Winchester packages this ammunition in convenient 20-round boxes, with 10 boxes per case (200 rounds total), so you can stock up for the season or grab just what you need for your next outing. If you run a 220 Swift and demand ammunition built to match your rifle's capabilities, Super-X delivers the velocity and consistency that have made it a standard-bearer for generations of serious shooters.
