This results in better penetration and a larger wound channel, making it more effective for taking down larger game. The .243 Winchester is still suitable for deer hunting, but it may require more precise shot placement.

Both cartridges are popular in competitive shooting, with the .308 Winchester being more commonly used in high-power rifle competitions. The .243 Winchester is often used in smaller bore competitions, such as varmint benchrest shooting.
