Product Overview
Winchester's Expedition Big Game loads the 140-grain Nosler AccuBond at 2950 feet per second, producing 2705 foot-pounds of muzzle energy. This represents a partnership between Winchester and Nosler, combining Winchester's loading expertise with Nosler's premium AccuBond bullet. The AccuBond features a polymer tip over a bonded lead core, fusing the jacket and core at a molecular level to prevent separation during penetration.
The 0.496 ballistic coefficient stands out as exceptional for a hunting bullet. This aerodynamic efficiency translates to flatter trajectory and reduced wind drift compared to conventional soft points, meaningful advantages for hunters taking shots past 300 yards. The boat-tail design contributes to this performance, reducing base drag to maintain velocity at extended range where traditional bullets begin losing effectiveness.
Elk hunters find particular value in the AccuBond's combination of long-range capability and bonded-core penetration. The bullet opens reliably from the polymer tip while the bonded construction keeps it together through heavy bone and muscle. This versatility makes it effective from whitetails through elk without changing ammunition—a practical advantage for Western hunters who might encounter either species on the same hunt.
- The bonded AccuBond core retains 60-70% of bullet weight through impact, penetrating deeper than conventional soft points when encountering heavy bone or muscle on elk-sized game.
- Outstanding 0.496 ballistic coefficient produces meaningfully flatter trajectory than most hunting bullets, reducing holdover requirements at distances where many hunters struggle.
- Polymer tip initiates consistent expansion while protecting the bullet profile during feeding and storage—reliable performance from the first round to the last.
- The 140-grain weight balances trajectory flatness with adequate sectional density for reliable penetration on game up to and including elk.
- Premium pricing reflects the Nosler bullet licensing—this ranks among the more expensive .270 Winchester options available.
- Velocity of 2950 fps runs slightly slower than some 130-grain alternatives, though the superior ballistic coefficient compensates at distance.
- Retail availability can be inconsistent—hunters should stock up rather than expecting to find boxes on the shelf the week before season.
