22LR high velocity - MV= 1260 fps
17 HMR MV= 2550 fps
A lot faster, huh?
.001 inches. Makes a difference depending on what you are shooting, how old the barrel is, etc..
Size and relative power. A .40 caliber bullet is .40 of an inch and the entire cartridge is 28.8 millimeters long. A .50 caliber (handgun) bullet is .50 of an inch and the entire cartridge is 40.99 millimeters long. The .50 caliber has more powder, more velocity, and more muzzle energy.
The .22 caliber bullet is ABOUT .22 inches wide. A .32 bullet is about .32 inches wide. The bullet will also be heavier due to size.
The most basic answer is, a 9mm has a smaller diameter. Other differences, (in most cases) less muzzle energy, smaller and lighter bullet, higher velocity.
The .22 bullet is smaller than the 9mm in size, (about 6mm) and is lighter in weight.
The .40 caliber bullet is a little larger in diameter and is a little heavier (under most circumstances). The .40 will usually have more powder, velocity, and muzzle energy. Also, the .40 is designed for use in a semi-automatic and the .38 is a revolver cartridge.
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.
metric vs inch measurement
The .45 caliber bullet is not used in a sniper rifle.
Size and amount of propellant
Muzzle velocity is the velocity of a bullet as it leaves the firearm's barrel, while recoil velocity is the backward momentum that the firearm experiences when the bullet is fired. Muzzle velocity determines the bullet's speed and trajectory, while recoil velocity affects the shooter's ability to control the firearm during and after firing.
Depends on caliber & velocity of the bullet.
