Winchester Deer Season XP 450 Bushmaster ammo pairs a 250-grain Extreme Point polymer tip with a streamlined jacket profile, producing 2200 fps and 2686 ft-lbs of energy at the muzzle. The large-diameter polymer tip initiates expansion on impact, while the tapered copper jacket controls penetration through hide, bone, and vitals. This is Winchester brass, boxer-primed, reloadable, and non-corrosive — purpose-built for hunters operating in straight-wall cartridge zones where the 450 Bushmaster dominates the whitetail woods.
Load Profile
The 250-grain Extreme Point projectile carries a G1 ballistic coefficient of 0.21, typical for a blunt-tipped hunting bullet optimized for terminal effect rather than long-range drift. At 100 yards, velocity remains supersonic and energy transfer is substantial. The alloyed lead core concentrates mass behind the expanding front section, balancing mushroom diameter with penetration depth. Brass cases headstamp cleanly and extract reliably in bolt-action and single-shot rifles chambered in 450 Bushmaster.
