In terms of energy:
The 9mm develops around 300 foot-pounds in the barrel, and the 7mm Mag develops around 3200 foot-pounds in the muzzle… which is 10 times more powerful than the 9mm. However, when it comes up close and personal, a 9mm would be the best choice for a self-defense situation due to its rapid firepower and superior maneuverability. Both would cause severe hearing damage in confined spaces, but the 9mm at 30,000 PSI would be less severe than the 60,000 PSI of the 7mm Mag. The largest bullet commonly loaded in the 9mm is 147 grain fired at around 950 fps, while the largest bullet commonly loaded in the 7mm is 175 grain fired at around 2800 fps. Both cartridges are designed for completely different purposes. The 7mm is a big game cartridge designed to take on large animals such as deer and elk, while the 9mm is designed as a close range self-defense cartridge. The biggest is not always the best.

a 9mm bullet is a larger diameter bullet, but a 7mm magazine is a much longer bullet and a much more powerful bullet. A 9mm is a revolver cartridge, while a 7mm magazine is a long range rifle cartridge. You can’t really compare the two, they are used for 2 different purposes. A 9mm magazine has an effective range of 50-60 meters and a 7mm magazine has an effective range of 500-600 meters. You are comparing apples and oranges here.
Of course, 9mm is larger than 7mm, the bore diameter of both firearms. But a 7mm Remington Magnum has about 3200 lb-ft of muzzle energy, compared to about 350 lb-ft for the 9mm pistol cartridge. Based on muzzle energy, the 7 Mag is nearly ten times more powerful than a 9mm. It also has a much greater effective range, roughly speaking: a few hundred meters for the 7mm against a few tens of meters for the 9mm fired with a pistol. A 9mm carbine or machine gun will have a slightly longer effective range.
It depends on what kind of 9mm and 7mm you mean and what you mean by bigger. The 9mm will always have a “wider” bullet.
However, 7mm rifle cartridges will be several times larger than a 9mm pistol holster.
And a 7mm rifle bullet, although thinner, is longer than a pistol bullet and can typically weigh more than 9mm.
And there are also 9mm rifle cartridges, usually old or rare versions like 9×57 etc.

7mm Mag is a rifle cartridge and is much more powerful than a 9mm Parabellum cartridge designed for handguns. However, 9mm fires a larger projectile but loses velocity. The 7mm has more powder behind it, so it gains more range and speed.
7mm is for long range shotguns, 9mm is for handguns…. neither could do the other’s job.
You are a bit confused aren’t you?
The 9mm is a pistol cartridge.
The 7mm Magnum is a rifle cartridge.
Apples and oranges.
The numbers represent the diameter of the ball.
9mm = approximately 0.36″, 7mm. = about 0.28″
This is only a small part of the story.
a 9mm throws a 112 gr. bullet at around 1200 FPS.
a 7mm. Magnum launches a 150 gr. bullet at around 3000 FPS.
What is “bigger”?
9mm is longer than 7mm, of course, but that’s not all. The 7mm Remington Magnum cartridge, for example, can launch a 160-grain bullet at over 2900 fps, and that long bullet will take the medium game a long way. A 9mm Parabellum pistol, on the other hand, typically fires a 115 grain bullet at around 1200 fps and is not suitable for medium games. 9mm rifle cartridges, available after World War I, fell out of favor and are barely seen today, where the 9.3mm continues to be popular in Europe and Africa, but less so in the United States. United. The closest you get in the US is the 35 Whelen, and for comparison the Whelen would typically fire a 225 grain bullet at about 2450 fps, about twice the weight at about twice the bullet speed of 225 grains at around 2450 fps. gun.
7mm Magnum down.* The 9mm is a pistol cartridge.* The 7mm Magnum is a rifle cartridge.* Big, big difference.* The 9mm can in no way compare or compete with the 7 mm Magnum.

It all depends on what you mean by “larger”. If you are talking about size, obviously the 9mm. If you are talking about power, give more information; but I’m going to assume you’re talking about the 9mm x 19, so the 7mm has more power.
9 is a bigger number than seven, so 9mm is bigger in DIAMETER, but 7mm is longer for some reason.
