Yes you can. The bore is the same size.

Yes, you can shoot .38 ammo in a .357 firearm. The .357 firearm is designed to also shoot .38 caliber ammunition.
No
Yes.
The short answer is no. You should not (and normally can't) fire any ammo in a gun other than what it is specifically designed to shoot. There are some exceptions, such as, you can fire 38 special in a gun designed for .357 magnum.
No. You should never try to load or fire any ammo into a gun other than what it is designed to fire. A .44 caliber gun is designed to fire .44 caliber ammo.
Yes, you can shoot .38 caliber ammunition in a .357 caliber firearm.
38 Special only, do not try to fire other types of 38 in it
Yes, you can shoot .38 caliber ammunition in a .357 revolver because the .357 revolver is designed to also shoot .38 caliber ammunition.
Yes If it is .38 special, this is correct. There are other types of .38 caliber other than .38 special, however.
The .357 Magnum cartridge is longer and much more powerful than the .38 Special. While .38 Special ammo CAN be safely fired in a .357 Magnum, the reverse is not true. It is dangerous to try this.
No. Ammo designated as .38 or .38 special is different than ammo designated as .380. .380 is designed for semi-auto handguns and .38 ammo is for revolvers.More to the point, the .38 Special has a longer case, and a larger diameter projectile. The .38 special bullet measures .357" diameter, the .380 measures .355" diameter. The .38 special is a 'rimmed' cartridge, and the .380 is 'rimless'. Luckily, .38 Special ammo will not fit in a .380 magazine, otherwise the results could be disastrous, possibly turning your .380 handgun into a hand grenade.
