40 Cal Ammo

40 cal ammo and 40 S&W ammunition refers to the same cartridge. .40 cal ammo (also known as .40 Smith & Wesson ammo) was originally developed as an in-house joint venture between Winchester and Smith & Wesson following discussions in 1989.  .40 cal ammunition is a new cartridge when compared to some other handgun cartridges which were developed more than 100 years ago.

.40 cal ammo came about as somewhat of a fluke.  The FBI was originally working with 10mm automatic ammo and had settled upon a load that met the agency’s criteria for bullet diameter, weight, and velocity.  The folks at cal and Winchester evaluated what the FBI was trying to accomplish and decided that said criteria could be met with a much shorter cartridge.  One that would facilitate accuracy and allow use of smaller, more carry-friendly pistols that had better grip frames.

Though it’s been 20 years since the introduction of .40 cal ammunition, none of the factory loads produced by the major munitions manufacturers took advantage of the .40 cal cartridge’s full potential to generate some serious velocity.  For such a small package, .40 cal ammo delivers a punch equivalent or better than .45 auto ammo.

Generating such power causes some problems, however.  Such a compact and powerful cartridge requires a high amount of pressure to be fully utilized.  That means lots of noise and a large muzzle blast when firing .40 cal ammo.  Nonetheless, plinkers and hunting enthusiasts the world over swear by .40 cal ammo.

The .40 S&W cartridge was created by both Smith & Wesson and Winchester and introduced on January 17, 1990 to be used with the S&W Model 4006 pistol.

The cartridge was derived from collaborative efforts between the FBI, Smith & Wesson, and Winchester after a historic shootout in Miami in 1986, during which the FBI’s revolvers were deemed incapable of effectively opposing automatic guns. Following this event, the FBI conducted a series of simulative tests consisting of eight tactical events; each one representing a scenario that FBI agents could possibly encounter. The tests ultimately spurred the development of a 10mm cartridge that is now known as the 40 S&W.

Cheap .40 S&W ammo was specifically developed for law enforcement and was originally meant to be a clone of the FBI’s 10mm cartridge. The 40 S&W cartridge has a cartridge case capacity of 1.25 ml and houses .40-inch diameter bullets. The overall case and cartridge length of the cheap 40 S&W ammo is somewhat shortened, but the rest of the dimensions are identical to the 10mm auto cartridge.

Even though cheap 40 S&W ammo has some distinct disadvantages, the cartridge has seen success in the U.S.  Although it has accuracy that is nearly identical to the 9mm and 10 mm auto, it does possess a slight energy advantage over the 9mm Parabellum and a lighter recoil than the 10 mm auto. In fact, with good JHP bullets, cheap 40 S&W ammo can produce heavy hits, even inducing hydrostatic shock in large living targets.

Although cheap 40 S&W ammo is only slightly above 9mm in dimensions, many assert that it greatly exceeds the capabilities of the 9mm Parabellum, and therefore, it is an optimal defensive cartridge for law enforcement. Cheap 40 S&W ammo generates about 350 to 500 foot-pounds of energy, surpassing the pressure of both the 9x19mm Parabellum and .45 ACP cartridges. While .40 cheap 40 S&W ammo is highly popular in U.S. law enforcement departments, it has never actually been used as a main cartridge in any military forces.

Cheap 40 S&W ammo could be one of the most effective handgun cartridges in existence, as it was  designed specifically by and for the United States law enforcement. Even though the cartridge was originally developed for law enforcement agencies, it can now be found in many gun shops around the country, and it is seen as a highly capable defensive cartridge, suitable for nearly any situation.

Cheap 40 cal ammo was introduced with the S&W Model 4006 pistol in early 1990s, and it was specifically designed to be used in American law enforcement. With the tactical aid of the FBI, Smith & Wesson and Winchester teamed up to create a pistol cartridge that could effectively compete with automatic weapons, which were becoming more prevalent in increasingly hostile urban situations.

While the 40 cal cartridge was being developed, the FBI created a series of eight test events, each of which represented different situations that FBI agents could possibly face in the field. The results yielded the introduction of a 10x22mm cartridge now commonly known as the 40 cal. While cheap 40 cal ammo is only slightly above the 9x19mm Parabellum cartridge, most still believe that it is much better than the 9mm cartridge.

The cartridge has a case capacity of 1.25 ml and contains 40-inch diameter rounds. The cartridge and case length of cheap 40 cal ammo is short when compared to that of the 10mm auto cartridge, but the rest of the dimensions are nearly identical.

While there are certain disadvantages to cheap 40 cal ammo, it has seen a great rise in popularity in the United States. Even though it is similar to the 9mm and 10 mm auto cartridges, it does have a higher energy output than the 9mm cartridge and a lighter recoil than the 10 mm auto cartridge. Cheap 40 cal ammo provides stopping power that is capable of producing hydrostatic shock in human targets.

40 cal ammo puts out about 350-500 ft-lbs of energy, and it slightly exceeds the PSI of the Parabellum and .45 ACP. While cheap 40 cal ammo is very popular in the United States, both amongst gun owners and the FBI, it has never been used by any military as a main defensive cartridge.

Cheap 40 cal ammo could be one of the most reliable and powerful handgun cartridges in current existence, partially attributed to the fact that it was designed specifically for the FBI. Although the ammo was originally developed for law enforcement agencies like the Federal Bureau of Investigations, it can be attained by any gun owner with a license, and it is seen as an ideal defensive handgun cartridge in almost any combat situation.
