Winchester Ammo X300SDS Deer Season XP Hunting 300 WSM 150 gr Extreme Point 20 Per Box/ 10 Cs

Winchester Deer Season XP is a 300 WSM hunting cartridge purpose-built for whitetail and mule deer at typical hunting ranges. This ammunition pairs Winchester's expertise in deer hunting with a specialized bullet design—the Extreme Point polymer-tipped projectile—engineered to maximize effectiveness on medium-sized game. Each box contains 20 rounds, and cases ship 10 boxes per case for hunters who stock up for the season.

The 150-grain Extreme Point bullet uses an oversized impact diameter at the tip, a design choice that increases the frontal area and energy transfer upon impact. The larger wound cavity this creates translates to more reliable knockdown, which matters when every shot counts in the field. With a muzzle velocity of 3260 fps and muzzle energy of 3539 ft-lbs, the ballistics are calibrated for the effective range where most deer hunters operate.

If you're hunting whitetail or muleys and want ammunition specifically formulated for the job rather than generic all-purpose rounds, Deer Season XP delivers the terminal performance and consistency Winchester built its reputation on. The polymer tip protects the bullet in the magazine and aids aerodynamics, while the Extreme Point design does the work when it counts.
