Winchester Power Point 450 Bushmaster ammo delivers 260 grains of jacketed soft point projectile at 2,693 ft-lbs of muzzle energy — engineered for the straight-wall cartridge regulations in Midwest hunting states. The 450 Bushmaster operates from AR-15 upper receivers chambered for the cartridge and bolt-action platforms, providing rifle-level energy inside 200 yards where most whitetail encounters occur. This load uses Winchester’s time-proven Power-Point bullet — a notched jacket that initiates expansion on impact while the soft lead core drives through shoulder bone and vitals.
Built for the Field
Winchester has been loading the Power-Point bullet since 1964, and the same expansion geometry appears in this 450 Bushmaster configuration. The 260-grain weight balances sectional density for tissue penetration with a flat enough trajectory for 150–200 yard shots from tree stands. Muzzle velocity sits around 2,200 fps from a 20-inch barrel, and the G1 ballistic coefficient of 0.191 means you’ll see 8–10 inches of drop at 200 yards with a 100-yard zero. Brass cases carry boxer primers for handloaders who want to reclaim components after a range session.

Expect consistent grouping at 100 yards from modern AR uppers built on the 450 Bushmaster spec. This load fits standard AR-15 magazines designed for the cartridge’s wider case diameter. For hunters operating in Ohio, Indiana, Iowa, and Michigan — jurisdictions that mandate straight-wall cartridges during rifle season — the 450 Bushmaster bridges the gap between shotgun slugs and bottleneck rifle rounds.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Observe the four rules of firearm safety at all times — treat every firearm as loaded, never point at anything you don’t intend to shoot, keep your finger off the trigger until ready to fire, and know your target and what lies beyond it.
- Verify that your state and county allow the use of 450 Bushmaster for the game species you intend to hunt — some jurisdictions specify minimum case length or energy thresholds.
- This ammunition contains lead components. Wash hands after handling, and follow California Proposition 65 guidance if you reside in or ship to California.
