WinchesterA(R) designed their Deer Season XP(TM) .30-30 Winchester 150 Grain Centerfire Rifle Ammo specifically for hunting whitetail deer - America's most popular big game animal. Winchester uses the XP (Extreme Point(TM)) bullet in this premium rifle ammunition that puts deer down instantly. The XP bullet has a high ballistic coefficient polymer tip for flat trajectory, but unique to the XP is that it has a much wider diameter where the polymer tip meets the jacket. The wider impact diameter hits hard and initiates expansion rapidly in the first 5-6 inches creating a large wound channel all the way though the animal. A tapered jacket reduces the risk of over expansion.
