Presumably if someone peened the mouth of the chamber with dry firing a rimfire, that could be fixed by re reaming the chamber but I am not gonna try it myself. Probably depends on how hard the barrel is. Like maybe they use softer steel on some rimfires as it is easier to machine and you don't need as strong a barrel as a centerfire. Then, you might end up peening the nose of the firing pin if the barrel is hard! Maybe you are more likely to break a thin firing pin or one with bends and sharp edges in it, than say a straight fat firing pin in a bolt action.
