have a competent gunsmith check the firearm. a lot of those old arisaka are either shooters or wall hangers depending on how rough they were treated. a LOT of ww2 and ww1 rifles were re-bored to make them more popular with american sportsmen when brought back. a decent smith can tell you if this has been done to yours. dont take it for granted that an old war rifle is still chambered as marked.
