Speer Impact 308 Winchester 172gr Hunting Bullets - 50 Count Box

The Speer Impact 172-grain hunting bullet delivers devastating terminal performance in 308 Winchester rifles, engineered with advanced polymer tip technology for consistent expansion at extended hunting ranges. This premium hunting projectile combines match-grade accuracy with reliable expansion characteristics that serious hunters demand for medium to large game pursuits.

What Makes This Different

The Speer Impact bullet features a proprietary polymer tip design that initiates controlled expansion upon impact while maintaining structural integrity through tough hide and bone. Unlike traditional soft-point bullets that can deform in flight, the Impact's aerodynamic tip maintains ballistic coefficient consistency shot after shot. The bullet's bonded core construction prevents jacket separation, ensuring maximum weight retention and deep penetration on game animals weighing 150-400 pounds.

Key Features

• 172-grain weight optimized for 308 Winchester ballistics and downrange energy retention
• Polymer tip design enhances ballistic coefficient and triggers reliable expansion
• Bonded core construction prevents jacket-core separation on heavy bone impacts
• Boat-tail base design reduces drag and improves long-range accuracy potential
• Controlled expansion engineered for 1.5x to 2x diameter mushrooming
• Premium brass cases with consistent neck tension and flash hole uniformity
• 50-round boxes provide adequate supply for load development and hunting seasons

Field testing demonstrates the Impact bullet maintains over 90% weight retention while creating wound channels 25-30% larger than comparable cup-and-core designs. The 172-grain weight provides optimal sectional density for 308 Winchester applications, delivering flat trajectory out to 300 yards while retaining sufficient energy for ethical harvests on elk, deer, and black bear. Temperature stability testing confirms reliable expansion performance from -20°F to 140°F ambient conditions.
