10mm
Generally speaking, the .45 caliber bullet is larger in diameter and heavier than a 9mm bullet.
The 9mm Lugar round is longer than a .380 Caliber, which is also equal to 9mm in diameter. The overall cartridge and the bullet is larger and the case contains more powder. The 9mm Lugar is more powerful. BTW, the .40 cal Smith and Wesson is also called a 10mm. It is only 1mm larger in diameter and a little more powerful than a 9mm Lugar.

The .40 is larger in diameter and (normally) has a heavier bullet.
The .357 Magnum is a larger cartridge, can fire a heavier bullet, and has about twice the energy of a 9mm Parabellum cartridge.
The .380 is a 9mm bullet. But, going with the assuming that you're comparing the .380 ACP (9x17mm) against the 9mm Luger/9mm Parabellum (9x19mm), the answer would be no.
10mm
A single 9mm bullet is about 3-6 cents. A 9mm Parabellum (Luger) CARTRIDGE is about .30-.55.
Typically, they're about even.. the bullet diameter .38 Special is larger by a negligible amount - .357, as opposed to .356 of the 9mm Parabellum.
Well, the 10mm bullet is WIDER than the 5.56mm, but the 5.56 round is longer than a 10mm round.
There are SEVERAL 9mm cartridges- the most common is probably the 9mm Parabellum (9mm Luger). A 9mm Parabellum BULLET (not cartridge) is typically slightly smaller than a .38 Special bullet- .356 instead of .357. The 9mm is frequently (not always) lighter- and shorter. Other 9mm cartridges (such as the 9mm Makarov) will have different bullets.
