The Speer Impact TB277H1 delivers controlled expansion and deep penetration for .277 caliber hunting applications. This 150-grain tipped bullet features Speer's advanced plated construction that maintains weight retention while creating devastating terminal performance on medium to large game.
What Makes This Different
The Impact bullet combines a polymer tip with a plated jacket design that outperforms traditional cup-and-core bullets. The tip initiates reliable expansion at velocities as low as 1600 fps, while the electroplated jacket prevents core separation that commonly occurs with standard hunting bullets. This construction delivers 85-90% weight retention compared to 60-70% typical of conventional designs.Key Features
