If you measure the bullet, that is all you measure, likewise the case. If measuring a loaded cartridge, you measure the length from the casehead to the bullet tip.

A cartridge or round packages the bullet, gunpowder and primer into a single metallic case precisely made to fit the firing chamber of a firearm. The primer is a small charge of impact-sensitive chemical that may be located at the centre of the case head (centerfire ammunition) or at its rim (rimfire ammunition). Electrically-fired cartridges have also been made. A cartridge without a bullet is called a blank.
Critical specifications include caliber, bullet weight, expected velocity, maximum pressure, headspace, overall length and primer type. The diameter of a bullet is measured either as a decimal fraction of an inch, or in millimeters. The length of a cartridge case may also be designated in millimeters.
Where two numbers are together, the second number can contain a variety of meanings. Frequently the first is the diameter (caliber) of the cartridge, and the second is the length of the cartridge case. For example, the 7.62 x 51 mm uses a bore diameter of 7.62 mm and has an overall case length of 51 mm. In the case of old blackpowder cartidges, the second number typically refers to the powder charge. For example, the .50-90 Sharps is a .50 caliber bullet (.512) with a nominal charge of 90 grains of blackpowder with a case length of 2.50 inches.

Both. The case has a maximum and a "trim to" length, and the whole cartridge has an overall length, often abbreviated to O.A.L. The case length, not O.A.L., is what's named in a cartridge designator like 5.56x45. But you are confusing things by calling the cartridge a bullet. The bullet is just the ball that gets shot out the end of the thing. The entire deal, case, primer, powder, and bullet, is called a cartridge.

You are just measuring the casing for the bullet. For example, when you see the ''8X57mm'' Mauser, the 57 is the measuring of the casing only.

You question is confusing. What are you trying to measure? caliber? case length? What do you want to measure and why? You need to go into more detail to have your question answered correctly.

If you are unaware of the of gun powder amount in the casing,your guess is exactly just that,a guess.
