Speer Grand Slam .308 Winchester 180gr Soft Point Ammo - 50 Rounds

The Speer Grand Slam .308 Winchester 180-grain ammunition delivers controlled expansion and deep penetration for big game hunting applications. This premium hunting cartridge features Speer's proven Grand Slam bullet design, engineered to maintain structural integrity through heavy bone and muscle.

What Makes This Different

The Grand Slam bullet construction utilizes a dual-core design with a protected soft point that initiates controlled expansion while the rear core maintains weight retention. Unlike standard soft point bullets that may fragment on heavy bone contact, the Grand Slam's bonded construction ensures consistent penetration through tough game. The 180-grain weight provides optimal sectional density for .308 Winchester applications, delivering approximately 15-20% better weight retention than conventional soft points.

Field performance testing shows consistent 1.5-2 MOA accuracy from quality bolt-action rifles, with reliable expansion at ranges from 50 to 400 yards. The Grand Slam bullet maintains its mushroom shape through heavy shoulder bones on elk and moose, while providing rapid expansion on deer-sized game. Temperature-stable powder formulation ensures consistent velocities across hunting conditions from -20°F to 120°F.
