It is how thick a bullet is, measured through the thickest part of the bullet, from one side to the other.
the caliber or gauge
diameter
The diameter of the bullets
The .45 caliber is bigger in diameter. If you mean weight. The .45 caliber is generally heavier. However there are some lightweight .45 caliber bullets that are lighter than .357 caliber bullets. Generally speaking .45 caliber bullets weigh between 180 - 230 grains. While .357 caliber bullets generally weigh between 158 - 180 grains. If you are talking about diameter, the .357 caliber bullets are approximately 0.357 inches in diameter. The .45 caliber is approximately 0.450 inches in diameter. Again, using this measure, the .45 caliber is the larger bullet.
Nobody makes a bullet that small. The smallest bullets are at least 4mm in diameter.
Diameter is the value used to rate things such as balls, bullets, and other round objects. So an 8mm ball has a diameter of 8 millimetres.
DO NOT ATTMEPT THIS!!!! There is a difference of .002 between the diameter of the projectiles.
The size of a given bullet is determined by its diameter, and its weight. The size must match the size of the barrel it will be fired from, and heavier bullets will be longer. With cast lead bullets, after casting they are pushed through a machine called a die. This squeezes the bullet down to a precise diameter- this is called SIZING.
You can use a 7.62 suppressor with a 30.06 bullet as bullets are normally of the same diameter.
The .50 caliber is larger in diameter than the .308. If you are referring to the bullets for the .50 BMG and the .308 Winchester, the .50 is MUCH heavier, and much longer than the .308.
NO. The .22 is a RIMFIRE cartridge, and is smaller in diameter than the .25 ACP- which is a center fire cartridge.
No. The diameter is the same, but the bullets still differ in length and weight.
