The M16 rifle uses the 5.56x45mm NATO cartridge. This lightweight round is designed for accuracy and high velocity, making it effective for military applications. The M16 can also chamber the .223 Remington, though the two cartridges are not identical.
Yes
5.56 The cartridge used in a M-16 is a 5.56mm caliber Nato round It is also referred to as .223 caliber Remington. The actual bullet is small, weighing between 46 to 52 grains and having a true diameter of .224 inches. Bullet and case are 5.4 cm long
m-16 fires .223
No, the two numbers are clearly different. In a more practical note, "7.62" is the diameter (in millimeters) of a bullet typically fired from a .30 caliber rifle such as a Chinese SKS or Russian AK-47 rifle, while "5.56" is the diameter (in millimeters) of a .223 caliber bullet like the M-16 or AR15 rifle.
No. They're not even remotely close to being the same. The two bullets are the same caliber but that is where the similarity ends. The M-16 bullet is about 3 times the length of a 22LR, completely different in shape, about 4 times the weight, etc. Also the cartridge used in the M-16 has more than 10 times the powder than a 22LR, giving much higher muzzle velocity.
The M-16 Carbine or M4 use a 5.56x45 Nato round or the civilian version .223 Remington

Well, it depends on what you mean. The caliber is "determined" at time of production based on whatever caliber the manufacturer wants it to be. The caliber can be determined later by looking on the barrel. The caliber will almost always be stamped somewhere on the barrel.
A bullet fired from an M-16 rifle typically travels at a speed of around 2,800 feet per second, which is approximately 853 meters per second.
No. Rifling is intended to stabilize the projectile.
The speed at which a bullet drops due to gravity depends on multiple factors, including the caliber of the bullet, the initial velocity at which it was fired, and the angle at which it was shot. Generally, bullets drop at a rate of about 9.8 m/s² due to gravity. Wind resistance can also influence the rate of drop.
