The 10mm is a modern pistol cartridge designed to be more powerful than the 9mm, and lends itself quite well to handgun hunting. Although respected for its power, the 10mm never garnered the level of mainstream acceptance that the .40 S&W did. Originating in Sweden, it has better stopping power than the 9mm, and better trajectory and range than the .45 ACP. With full power loads, the 10mm cartridge can be used for deer, bear, and even boar. The 10mm does have a reputation for possibly battering guns, though, since there is so much barrel pressure. As often happens, modern trends are influenced by the movies. The 10mm round rose in popularity when "Sonny Crockett" was seen using a 10mm Bren Ten pistol on TV's popular "Miami Vice". Pistols chambered in 10mm tend to have a niche market, and ammunition tends to be more expensive and harder to find than the common .40 S&W. In fact, at the time of this writing, the price of factory loaded 10mm ammo can go as high as $37.00 for 25 rounds. 10mm rounds have a muzzle velocity of 1,300 ft / sec to 1,600 ft / sec, and an impact energy of 728 ft lbs to 767 ft lbs.
