Winchester Deer Season XP Rifle Ammunition .300 WSM 180gr PT 2900 fps 20/ct

Winchester Deer Season XP rifle ammunition in .300 WSM is purpose-built for hunters who demand reliable, ethical shot placement on whitetail and other deer-sized game. This 180-grain polymer-tip load delivers 2900 fps muzzle velocity and 3361 foot-pounds of energy—ballistics engineered from the ground up for the .300 WSM's capabilities. If you're running a modern bolt-action or semi-auto chambered in this magnum short action, Winchester Deer Season XP gives you the terminal performance and downrange efficiency that separates a clean harvest from a wounded animal.

The Extreme Point bullet design is where Deer Season XP earns its reputation. The tapered copper jacket and alloyed lead core work together to expand reliably across the typical hunting ranges where most deer are taken, while the large-diameter polymer tip initiates rapid expansion on impact. Winchester's ballistic profile—optimized with a 0.422 G1 coefficient—means your shot retains velocity and energy better at distance, letting you stretch your effective range without sacrificing accuracy or lethality. This is not generic ammo repackaged for deer; every component from primer to case was selected for this specific mission.

Loaded in new-production brass with boxer primers, Winchester Deer Season XP is fully reloadable if you handload. Twenty rounds per box fits a standard ammo can or hunter's pack, and the straightforward ballistics of a supersonic load mean you'll zero your rifle once and hunt with confidence. For hunters in .300 WSM country—where you need that magnum edge in open terrain or where a longer shot might be your only shot—this is the ammunition that delivers when it counts.
