Sierra Steps Up Their Game With Gamechanger Ammunition

After 70 years of bullet innovation, Sierra is entering the world of ammunition. You heard that right, now you can get the same accuracy and consistency that Sierra offers, without having to reload your own ammo. Their new Gamechanger Ammunition comes complete with their new Gamechanger bullet. Gamechanger ammunition combines the match grade accuracy you crave with the terminal performance that you need when in the field.

The Gamechanger Bullet has a boat tail design for accuracy and stability, optimal jacket wall thickness to help control expansion and retain weight, precisely engineered jacket wall concentricity, turned ogive for better BC's, open pocket design for further expansion of the lead core, and a synthetic tip for smooth chambering, better flight, and instant expansion.

Outside of bullets and ammunition, you can expect to see a new reloading manual from Sierra around April 2019, while the app version is already available for download on Android and Apple devices.
