If you actually mean power (energy), then yes several of the lighter bullet weights are more powerful.
If you just mean a heavier bullet, yes, you can get a 50 gr bullet.
A 44 magnum is more powerful than a 45calibur
Magnum simply means a more powerful cartridge. Some shotguns fire magnum cartridges. You need to define the "Magnum" you are trying to compare with a shotgun.
No.
The Desert Eagle was made in several calibers- one of which WAS the .44 magnum.
Just as a magnum wine bottle is larger than a standard bottle, the firearms industry used the term magnum to refer to a cartridge that is more powerful than the standard cartridge.
The .460 S&W Magnum is generally more powerful than the .44 Magnum. The .460 has a larger case capacity and can fire heavier bullets at higher velocities, resulting in greater energy and stopping power. While the .44 Magnum is a formidable round, the .460 is designed for larger game and more extreme conditions, making it the more powerful option overall.
A magnum gun is a gun that will shoot a magnum cartridge, and that cartridge will have magnum in its' name. It is just a moniker that infers more powerful cartridge, but the name itself has little or no significance...other than as a marketing tool. One that will propel a projectile at significantly more velocity than a regular one.
Two unrelated terms. A magnum is a cartridge more powerful than the original cartridge. Carbine is a short barreled rifle. Some carbines are chambered for magnum cartridges.
I'd imagine that at closer ranges (like 50 yards or closer) the .44 Magnum is much more powerful. But it is a handgun round, which loses power fairly quickly. The M-16 shoots a small diameter bullet (.223) but is accurate and more powerful at a longer distance.
No, .38 Special and .357 Magnum cartridges are not interchangeable due to differences in size and pressure. The .357 Magnum is longer and more powerful than the .38 Special, so using a .38 Special cartridge in a .357 Magnum firearm can be dangerous.
Yes, the .500 S&W Magnum is a significantly more powerful cartridge than the .50 Action Express used in .50 cal. models of the Desert Eagle.
It's more powerful. As for "better", it really comes down to what your needs are. The lighter recoil of the .38 presents advantages which at time may outweigh the advantages of having the more powerful .357 Magnum.
