What does the size of a bullet mean?
Caliber is used to describe the size of a rifle or handgun bore and the size of cartridges designed for different bores. In some cases, the caliber is given as the diameter of the bullet, which is the distance between the grooves.
Why are bullets strange sizes?
The bullet is not made to fit the bore of the firearm, however. All rifles and almost all handguns have rifling grooves cut into the barrel, and if the bullet is not large enough to fill these grooves, then hot gas will escape around the bullet through the rifling grooves.
Are bigger or smaller 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.
How do you make all bullets the same size?

What determines the form factor of a bullet?
Only the nose length, nose profile, meplat diameter, boat tail angle and boat tail length dictate what the drag and form factor of the bullet will be. This bullet has a form factor of 1.006, which is only 0.6\% more drag than the G7 standard; essentially identical.
Are there a lot of different sizes of bullets?
There are a lot of sizes out there, making buying of bullets a little complicated. Newbies in the shooting world will get confused, especially because of the lingo involved in buying the right bullet size. This is a complete bullet guide of 2021: sizes, calibers and types.
What is the ballistic coefficient of a bullet?
The objective of this article is to highlight another empowering analysis feature of the G7 paradigm: form factors. In words, the Ballistic Coefficient of a bullet is it’s sectional density divided by its form factor. Sectional density is easy to calculate because it simply depends on the bullets caliber and weight.
What happens if you shoot a bullet with a smaller caliber?
The smaller of these calibers can bounce around and inside the human’s body. This can cause tearing of body organs and ligaments. The caliber has a bullet weight of 30-40 grains.
