More powerful loadings can equal or exceed the performance of the. The performance of the 9mm Luger round does not even come close. How did the FBI get hooked up with Cooper? Special Operations Forces. Cooper himself was not only a shooter of renown, but he was also a businessman extraordinaire, and he leveraged his longstanding trusted relationship with the FBI to market his 10mm Auto round and the pistol he had chosen to fire it.

The FBI had a problem and Cooper offered an immediate solution. So what happened? However, there was a saving grace - the FBI and Hollywood. An additional detractor for the FBI was the high cost and low availability in quantity of 10mm Auto ammunition for training. The FBI quickly realized it needed a high-performance pistol round with less recoil that was cheaper and available, but they were now stuck with the 10mm Auto. Sadly, it all came to an abrupt finale and somewhat happy ending in the early s with the advent of the.

As early as , the FBI was testing various 10mm Auto reduced loads in an attempt to decrease its objectionable recoil. This fact made it singularly ideal for law enforcement use, but its undesirable recoil needed mitigation. This load remains in production by various ammunition manufacturers today.

There was, however, an inherent problem using this lighter load not identified because the FBI did only technical testing under ideal range conditions and no operational testing there is a huge purposeful difference between the two.

The lighter load resulted in pistol feed and ejection problems. Failures were especially evident when the pistol was fired in an up or down vertical position as one might when be engaging an opponent on a roof or down a stairwell. The problem with downloading reducing the propellant quantity in any cartridge is the airspace that results inside the cartridge case.

If you visualize a cartridge that is fully loaded with propellant, there is little to no air space between the top of the powder column and the base of the bullet, with the bullet installed at its specified depth in the cartridge case. This is the optimal physical scenario for full propellant combustion and its subsequent development of the maximum pressure necessary to optimally propel the bullet down range.

Bullet velocity is a product of the velocity of propellant combustion burn speed. Therefore, bullet velocity cannot exceed its propellant pressure velocity.

Airspace leads to radical propellant burn pressures and inherent inaccuracy because of pressure fluctuations. So, how do you fix that problem? The answer is to reduce the cartridge case length and eliminate the air space. At this point myth again carries the story. Many believe the FBI went to Smith and Wesson and Winchester, and they jointly developed the smaller case length cartridge resulting in.

The facts show otherwise. It may also be appropriate to point out that Industry develops stuff.
