AP diameter of 9mm in the midline means the front-to-back distance in the middle of the structure is less than a half inch.
The 9mm round measures .356 inch in diameter. a 380 is 95 gr 9mm 124gr 40 is180 gr 45 is 230 gr
.355
"Powerful" is somewhat of a subective term, but the answer is yes. 5.56 is a rifle cartridge and 9mm, assuming you mean 9mm parabellum, is a handgun cartridge. Under normal circumstances, bullets fired from rifles will have more velocity and more muzzle energy than bullets fired from handguns.
That's a difficult question to answer, because different cartridges have different specifications, and muzzle energy and velocity are different when fired from guns with different barrel lengths. One particular 9mm cartridge may be "more powerful" than say, one particular 40 caliber cartridge but "less powerful" than another.
9mm target ammunition is commonly less expensive than .45 ACP.
Less powder for its size.
No, the .380 has less power than the 9mm or the .45 .
.38 Special- 9mm is more powerful. ,357 Magnum- 9mm is less powerful.
The .380 IS a 9mm- a 9mm Short (also called 9mm Kurz or Corto). There are more than a dozen different 9mm cartridges. Most people mean the 9mm Parabellum (also called 9mm Luger) when they say 9mm. The 9mm Parabellum IS a longer cartridge than the .380 .
No. There are more than a dozen DIFFERENT "9mm" cartridges, and they do not interchange. The most common is 9mm Parabellum- also known as 9mm Luger or 9x19. It does NOT interchange with 9mm Kurz, 9mm Corto, 9mm Makarov, 9mm Ultra, etc.
Depends to some degree on how the cartridge is loaded, and the weight of the gun firing it- heavy guns recoil less. Recoil is similar to a .38 Special- more than a .22, less than a .45. My granddaughter is in her mid teens and shoots my Browning Hi Power 9mm, so recoil is not that bad.
The actual power of any given cartridge is based on speed and weight of the bullet. There are multiple different loads for the 9mm Parabellum, and for the .45 ACP. HOWEVER- in general, the 9mm Parabellum has a higher energy than the .45 ACP. Search Wikipedia for 9mm Parabellum, and for .45 ACP. Scroll down for energy figures on the left. It should be noted that almost all .45 loads have heavier bullets, and the .45 ACP is generally considered to have greater "stopping" power than the 9mm.
No, an A380 bullet is significantly larger and more powerful than a 9mm bullet. The A380 bullet is typically used in aircraft cannons and has much greater stopping power due to its higher velocity and larger size.
It is 1mm less than the size of a quarter. 1/10 less...pretty freaking huge
A 9mm pencil lead is thicker than a 7mm pencil lead.
Technically, a 9mm bullet has NO energy, since the bullet is the metal part that leaves the muzzle of the gun when fired. However, the 9mm Parabellum cartridge does have energy. The exact energy varies with the loading of that cartridge- but about 420 ft lbs of energy at the muzzle. Typically this is more than a .38 Special cartridge, less than a .357 Magnum cartridge.
