10mm Auto (10x22mm)

    The 10mm Auto (10x22mm) is a semi-auto pistol cartridge introduced in 1983. 
It was first used by FBI and Police, but was later decommitioned, because it was concluded that this bullet has excess recoil to be used by Police officer in active combat, also the guns created for this bullet were too large for certain short handed users.

  To counter this .40 S&W was made, which became rapidly popular because of its size and ballistic capablity. The 10mm auto never got the popularity of its shorter version .40 S&W.
How ever some gun enthusiasts still perfer the 10mm auto.

Performance:
   A full performance 10mm auto bullet produces slightly more energy then .357 magnum. The bullet is considered to be high velocity with very less curved flight path. 
At its lighter loadings the duplicate the performance of .40 S&W  but its more power full loadings can equal or exceed the performance of .357 Magnum. 

The 10mm auto is marketed for hunting, and tactical self defence use. The bullet is used as high power calibre defence against humans and animals. 
And its perfered by those who want a higher capacity power full semi-auto gun instead of a magnum revolver. 

.45 GAP

    This pistol cartridge was designed specifically on the request of Glock gun manufacturers. It was designed because the Glock wanted a bullet with similar ballistic performance as .45 ACP but could also fit in more compact pistols. 
The GAP there fore means Glock Automatic Pistols. 

.45 GAP compaired to .45 ACP

   The .45 GAP has the same diameter as .45 ACP but is shorter compared to it, also it has shorter primer compared to .45 ACP. Initial development of .45 GAP had lighter bullet compared to .45 ACP, there fore .45 GAP operates at higher pressure. But because of the smaller size of this bullet the increased pressure of this cartridge was to be obtained through selection of powder only. 
The maximum bullet weight for .45 GAP is 15 Grams.

  The .45 GAP is quite popular with both civil and law enforcing agencies because of its ability to have ballistic performance of .45 ACP while having its smaller size. Making it a good choice for concealed carry weapons, and machine pistols.

.380 ACP (9x17mm)

   The .380 ACP (automatic colt pistol) is a rimless straight walled cartridge designed by John browning. 

     This bullet was designed for early blowback pistols which lacked barrel locking mechanism. The locking mechanism is unnecessary for .380 ACP since it has relatively low bolt thrust. The recoil spring and slide are enough to buffer the recoil energy of the round. 

 Since this makes the production of the gun using this bullet simpler, there by reducing the production cost making the gun cheaper. It also allows the barrel to be permanently fixed with the frame, this promotes the accuracy significantly.
Alot of modern weapons are chambered for this bullet including machine-pistols and sub machine guns.

Bullet dimensions

  This bullet has seen many wars as its most popular uses were by German officers in WW2 in Walther PPK and by Italian in Beretta M1934.
  How ever its not very suitable for active combat because it doesn't provide suitable penetration for combat. But because of its small size and low recoil its quite popular in civilian market for self defence, and is a viable choice for concealed carry pistols. 

Performance:
   The .380 ACP is light and compact but also has relatively short range and stopping power. But even so it remains popular among ammature shooters who want a light weight gun with manageable recoil.

.357 SIG

   The .357 SIG is the product of Sig Sauer. It is actually based on .40 S&W, and has a good reputation for both accuracy and stopping power. 
   

  It was developed in 1994, and named "357" because it was intended to duplicate the performance of .357 Magnum bullet (fired through a 4 inch revolver), in a cartridge designed to be used in a semi-auto pistol. 
  

  The .40 S&W guns can be converted to .357 SIG by a simple replacing of barrel, but some times recoil spring must be changed as well. Pistols with strong recoil springs can easily be converted by a simple barrel replacement. 
.40 S&W magazines can also feed .357 SIG without any difficulty. But before thinking of conversion to this bullet it must be kept in mind that .357 SIG is loaded at higher pressure then .40 S&W, and that is why its not suitable for all .40 S&W guns because of increased bolt thrust.

  Because of this bullet was designed to replace .357 magnum bullet, it does provide an equivalent performance with the ability to be used with semi-auto pistols, this gained this bullet high popularity and respect among civil and law enforcing agencies. 

  How ever this bullet is not as popular as 9mm parabellum, .40 S&W or .45 ACP. There fore only those who actually know about this bullet prefer it. Also it is said that this bullet is only available form high grade gun shops and may not be available from some local town gun shop.

.500 S&W magnum (12.7x41 mm)

     The .500 Magnum (12.7x41 mm) is a semi-rimmed bullet developed by car-bon and S&W's X-GUN engineering team, for the use of S&W model 500 revolver.

.500 S&W in the middle

Performance:

    The .500 S&W is the most powerful hand gun bullet in the world by the virtue of the muzzle energy it generates, there are bullet types for this gun which are:

1. 21.1 Grams having 550 m/s velocity
2. 26 Grams having 495 m/s velocity
3. 29 Grams having 495 m/s velocity
4. 23 Grams having 602 m/s velocity (top performer)

  This bullet can produce 4,109 J of energy, it is clammed to be the most powerful hand gun bullet ever made, and delevers almost the same power as a shot gun slug.

  The .500 S&W because of its super bullet strength has a very high recoil energy and very high recoil velocity, because of this it throws the revolver upwards when the bullet is fired. 

This is why the S&W model 500 is equipped with a muzzle flash compensator and Hogue and Sarbothane grips, also the revolver's considerable weight plays a major role in reducing this effect.

  

  The Bullet's dimensions

  This bullet is extremely strong, so strong that it can open a big hole in a bear, so if you wana go hunting this is the gun that should be with you, or if you wana scare the shit out of some thug who thinks he can scare you trust me its noise is enough to do the job. :P

.50 calibre BMG (12.7x99 mm)

     .50 Calibre (12.7x99 mm) or also called .50 BMG or (Browning machine gun) was first used in .50 calibre browning machine gun in 1921. 
   This bullet is mostly used by heavy calibre machine guns how ever its also used by Sniper rifles, and in sniper rifles this bullet made the world record for the longest range kill ever.

Since this bullet is too strong and is able to produce 18,000 J of energy it can easily penetrate light armour in its AP mode, and can hit extreme long range targets, because of its high ballistic co-efficient this bullet suffers very less accuracy loss at long range targets. 

Bullet Dimensions

Because if this bullets usefulness and its large list of military applications this bullet is made into variety of types. like FMJ, tracers, Armour pearcing, sabot APs, Incendiary, Ball and even Armour pearcing explosive incendiary (APEI).

.50 Calibre ammo types:

one on most right (Ball type)

Red Tip: tracer

Silver pointed: SLAP

Silver pointed and red bodied: tracer Slap

Black tip: Armour pearcing

Blue Tip: Incendiary

Silver tip: Armour pearcing incendiary.

Red-Yellow Tip: SPOTTER ROUND

Green-Silver tip: MK211 Multi-purpose round.

.50 AE (12.7x33 mm)

   .50 AE is a large caliber hand gun bullet, and is the most powerful handgun bullet ever made. 

.50 AE next to .22 LR

   The Desert eagle was the first gun ever chambered with this bullet, actually the cartridge is 0.547 inch (13.6 mm) and therefore Desert eagle mark XIX was designed specifically for this bullet.

.50 AE next to .32 acp

Performance:
   The maximum chamber pressure for this bullet is 248 MPa and can produce almost 2490 J of energy, 
This bullet is commonly used to hunt big targets like bears, and considered unnecessary powerful for tactical defence, but you can imagine if it can easily kill armoured bares what will it do to humans. :P
  The hollow points of this bullets can easily break a wide hole in trees, and can even break their trunks down, and FMJ bullets can go right through a 4 people standing in line.

.50 AE (left) compared to other popular bullets of handguns 9mm (right) looks puny compaired to it.
