Winchester Varmint X Ammunition 223 Remington 40 Grain Polymer Tip 20RD

Winchester Varmint X ammunition in 223 Remington delivers the speed and terminal performance predator and varmint hunters demand. This 40-grain polymer-tip load launches at 3600 fps with 1151 ft-lbs of muzzle energy—fast enough to put down prairie dogs, coyotes, and other varmints cleanly and reliably. The polymer tip initiates rapid expansion on impact, while Winchester's manufacturing heritage ensures consistent, dependable performance across your hunting seasons.

Whether you're working rodent-heavy rangeland, managing predator populations, or heading out for a long day of varmint control, this ammunition pairs Winchester's reputation for consistency with modern bullet design. The 40-grain weight strikes a practical balance: light enough for flat trajectory and quick target acquisition, heavy enough to carry energy downrange. Each box contains 20 rounds, making it convenient to reload your magazine or your range bag.

Varmint X is built to perform in real hunting conditions, not just on paper. If you're serious about predator and varmint hunting and want ammunition engineered specifically for explosive terminal performance in that role, Winchester Varmint X deserves a place in your ammunition locker.
