The Winchester Expedition Big Game Long Range 270 Winchester load delivers the flat trajectory and energy retention required for shots past 400 yards on elk, mule deer, and trophy antelope. Loaded with a 150-grain Nosler AccuBond Long Range bonded polymer tip, this 270 Winchester hunting ammo leaves the muzzle at 2900 feet per second with 2801 foot-pounds of energy. The high ballistic coefficient of 0.625 reduces wind drift and maintains supersonic velocity well beyond conventional cup-and-core bullets. The bonded construction prevents core-jacket separation when the bullet encounters heavy shoulder bones or quartering angles, ensuring consistent weight retention and penetration depth across a range of impact velocities.
Load Profile
Winchester engineers this load around the Nosler AccuBond Long Range projectile — a boat-tail design with a sleek ogive that produces match-grade accuracy in standard SAAMI chambers without requiring jump adjustment. The bonding process eliminates the fragmentation issues associated with many high-BC hunting bullets when impact velocities exceed 2800 fps at close range. The nickel-plated brass resists corrosion in wet-weather hunts and feeds reliably in bolt-actions and semi-autos. Boxer primers allow for straightforward reloading when you want to develop custom loads using once-fired Winchester brass. The sectional density of 0.279 provides adequate penetration on medium to large game when shot placement is correct.

This load fits hunters who zero at 200 yards and dial elevation for shots from 300 to 500 yards on open-country game. The high BC minimizes wind drift compared to lighter 130-grain bullets, and the bonded construction handles close-range impacts without fragmenting.

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.
- Treat every firearm as if it is loaded. Keep the muzzle pointed in a safe direction at all times. Keep your finger off the trigger until your sights are on target and you have made the decision to fire. Be sure of your target and what is beyond it.
- Verify that your rifle is chambered for 270 Winchester before loading. Check your state and local laws for hunting ammunition restrictions, including lead-free requirements in certain zones.
- This ammunition contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands thoroughly after handling ammunition and fired cases.
