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.
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.
The main difference between a 9mm and a .45 caliber bullet is the diameter. A 9mm bullet has a diameter of 9 millimeters, while a .45 caliber bullet has a diameter of .45 inches. The .45 caliber bullet is larger and generally heavier than the 9mm bullet, resulting in differences in recoil, speed, and stopping power.
A single 9mm bullet is about 3-6 cents. A 9mm Parabellum (Luger) CARTRIDGE is about .30-.55.
All else being equal, the one that has more foot pounds of energy.
There are SEVERAL 9mm cartridges- the most common is probably the 9mm Parabellum (9mm Luger). A 9mm Parabellum BULLET (not cartridge) is typically slightly smaller than a .38 Special bullet- .356 instead of .357. The 9mm is frequently (not always) lighter- and shorter. Other 9mm cartridges (such as the 9mm Makarov) will have different bullets.
.38 Special- 9mm is more powerful. ,357 Magnum- 9mm is less powerful.
380 and 9mm ammunition IS NOT INTERCHANGEABLE.
No
The 9mm Lugar round is longer than a .380 Caliber, which is also equal to 9mm in diameter. The overall cartridge and the bullet is larger and the case contains more powder. The 9mm Lugar is more powerful. BTW, the .40 cal Smith and Wesson is also called a 10mm. It is only 1mm larger in diameter and a little more powerful than a 9mm Lugar.
No, the bullet will not seat.
The 9mm round in loaded with a bullet diameter of .356"in.
The .22 bullet is smaller than the 9mm in size, (about 6mm) and is lighter in weight.
