The 10mm Automatic is a powerful semi auto cartridge. With the proper bullet in capable hands it is suitable for hunting medium size game at close range. Although it has been used on large dangerous game including Cape buffalo and the great bears it is not ideal for such game. The round is capable of pushing a 180 grain bullet to 1,300 FPS from a 5” barrel. This exceeds the power of a .357 magnum by a good margin and is closely on the heels of a .41 magnum. Bullets are .400” diameter and range from 125 grains to 220 grains. Once in service with the FBI, it is now considered excessive in recoil and stopping power for law enforcement use. Hand guns and ammunition is available from most major manufactures. — Craig Boddington
