Speer Impact Bullet .308 190 Grain Rifle Bullet 50. The Speer Impact bullet blends tough molecularly bonded construction with a high ballistic coefficient. Its groundbreaking Slipstream polymer tip provides a perfect aerodynamic meplat and its hollow core initiates expansion at velocities 200 fps lower than comparable designs. The combination results in deep penetration at mid-range as well as extreme accuracy and consistent low-velocity expansion at long distances.
