Ammunition size is usually expressed in terms of calibre, which is the diameter of the projectile as measured in millimetres or inches. In general, projectiles less than 20 mm or . 60 inch in diameter are classified as small-arm, and larger calibres are considered artillery.
How are bullets sized?
For guns, “caliber” means the diameter of the barrel and thus the diameter of the bullet that is going through it. Usually in inches or mm. Also for terminology’s sake, “bullet” just means the metal projectile, while the entire thing is called a cartridge. Here’s some common 9mm bullets.
What is the difference in ammunition size?
Bullet sizes do matter. When we refer to caliber, as we mentioned earlier, we are talking about the internal diameter of the barrel and by extension the bullet’s diameter. Technically speaking bullets are actually ever so slightly bigger than the barrel or bore.
Are bigger bullets better?
In general, as with most things, “bigger is better”. But “bigger” (in a bullet) leads to a lot of undesirable things happening. The larger the bullet (caliber), the more air it must push out of the way during flight. This causes the bullet to slow down, impacting it’s accuracy and distance.
