Can you shoot .380 bullets out of a .357 revolver?

Are you asking about shooting the .380 ACP cartridge in a Taurus revolver designed for the 357 magnum cartridge ? ? ?
OR
Are you asking about reloading .380 ACP BULLETS (the .355" diameter projectile) into a 357 Magnum case (designed for .357" bullets) ? ? ?

Don't try to do either !

Yes. 38 Special cartridges are OK in a revolver chambered for 357 magnum.
