Caliber refers to the diameter of a bullet (bullet is the part of a cartridge that is fired out of the gun). A .223 caliber bullet is .223 inches across. It is normally used as a rifle cartridge. a .45 caliber bullet is more than twice as wide as a .223, and is usually used in pistols. The .223 is lighter- it weighs about 1/4 of a .45 bullet, and they are different shapes- .223 is usually pointed, the .45 is rounded.
It varies, depending on barrel length, bullet weight, etc, but on the average-Maximum effective range: 500 metersMaximum range: 3534 meters
There isn't enough info to give a correct answer. What grain bullet? What type of bullet? What is the initial velocity? How high are your sights about the bore axis? What range is your far zero?
Any firearm chambered for .223 or 5.56mm
Only .223 ammo. There are different bullet weights.
.223 inches in diameter, typically 45 to 55 grains for the .223 Remington, and 80 grains for the .223 Wylde.
No. Not even close.
Generally, a bullet's caliber has NOTHING to do with its accuracy. So your question cannot be answered. However, a 9mm is usually a handgun round, used at close range (0-15meters). A .223 is typically used at longer ranges, but could be used close-up as well. At distances greater than 20 meters, up to 500 meters, the .223 will be more accurate, if the weapon is dialed-in.

Compared to the 223 Remington, the case volume of the 308 Winchester is increased by approximately 80%. The 308 Win now fires a larger bullet and maintains long-range speed, but at the expense of recoil.
