10MM 200 Grain Wide Flat Nose Hard Cast Bear Defense- The 10mm Auto (10×25mm) is a powerful semi-automatic pistol cartridge first developed by American Jeff Cooper and introduced in 1983 with the Bren Ten pistol.
Although it was selected for service by the Federal Bureau of Investigation in 1989 from the aftermath of the 1986 FBI Miami shootout, the cartridge was later decommissioned (except by the Hostage Rescue Team and Special Weapons and Tactics Teams) after their Firearms Training Unit eventually concluded that its recoil was excessive in terms of training for average agents and police officers’ competency of use and qualification, and that the pistols chambered for the cartridge were too large for some small-handed individuals.
These issues led to the creation of and following replacement by a shorter version of the 10mm that exists today as the .40 S&W, and while the 10mm never attained the mainstream success of this compact variant, there is still an enthusiastic group of supporters and users.
At full potential, the 10mm Auto produces energy slightly higher than an average .357 Magnum load and below standard .41 Magnum rounds. The cartridge is considered to be high-velocity, giving it a less-curved flight path upon firing (also termed “flat-shooting”) relative to other handgun cartridges. In its lighter loadings, the 10mm Auto is an exact duplicate of the .40 S&W cartridge. More powerful loadings can equal or exceed the performance of the .357 Magnum, and retain more kinetic energy at 100 yards than the .45 ACP has at the muzzle.
The 10mm outperforms the .40 S&W by 270–300 ft/s (82–91 m/s) for similar bullet weights when using available full power loads, as opposed to the “10mm FBI” level loads still found in some ammunition catalogs. This result is due to the 10mm Auto’s higher SAAMI pressure rating of 37,500 psi (259 MPa), as opposed to 35,000 psi (240 MPa) for the .40 S&W, and the larger case capacity, which allows the use of heavier bullets and more smokeless powder. The 10mm Auto is marketed for hunting, defensive, and tactical use and is one of the few semi-automatic, rimless cartridges that is legal for hunting white-tailed deer in many U.S. states. The round makes the “Major” power factor ranking in the International Practical Shooting Confederation, even in lighter loadings.
