The Liberty OverWatch .357 Magnum 70gr load (Liberty part no. LAOW357701830) is a 20-round box from Liberty Ammunition. It sends a light 70-grain projectile out at 1830 fps for 520 foot-pounds of muzzle energy. The light bullet keeps recoil more controllable than traditional heavy magnum loads, which helps in compact revolvers carried for protection. Liberty rates accuracy at 1 inch at 25 meters, so it is also a capable choice for range work.
