It depends on a lot of things. The longer the barrel is the more powerful and accurate the round is going to be. Secondly, the construction of the bullet counts as well. If you are shooting with a hollow-point, that probably isn't as good as a solid round because the hollow-point will break up instead of penetrate. A hollow-point is more likely to break up before reaching vital areas of anatomy that can stop a bear.
So the bottom line is can you stop a bear with a 357 magnum? With a hollow-point light 110grain 357 cartridge and an 2 inch barrel I would not count on it. If you have a solid point 357 180 grain cartridge and an 8 inch barrel you would be a lot more likely to stop a bear. If you really want to stop a bear you are better off with a shot gun loaded with slugs or a rifle rather than a 357 magnum. Killing a bear with a 357 magnum is a real crap-shoot, especially with shorter barrels and less powerful hollow-point cartridges.
That's my best answer.
Whatever the market will bear.
No, there are .357 caliber bullets that are not magnum, but they are in the minority.
its not a 357 maximum its a 357 magnum i would know i have one ruger .357 magnum speed 6 but yes you can as long as you have a hunting permit
.357 Magnum will have more recoil.
No. You can get a Sig P229 that will fire .357 Sig, but that is not the same as .357 magnum.
If the weapon is chambered in 357 Magnum, you can fire the round in it.
The .357 part of the name means that the bullet diameter .357 inches. I do not know what the "Magnum" means in the name.
