Well, to be completely accurate, a .38 revolver can't fire .357 magnum rounds.
But they used to , the .357 design was changed for exactly the reason that it fitted the same as a .38 special and the resuts could be unpleasant .

Tribes is completely out of his depth here
OK Mr smarty , when is a .22 not a .22 ? is it perhaps on the same occasion that a .45 isn't a .45 ?
