Owning a firearm in an obscure, obsolete, hard to find caliber can be a bit frustrating and basically requires you to reload for it. Sometimes even finding brass or bullets for it can be all but impossible too. As long as you are willing to do the reloading and can pony up for a lifetime supply of components, it is doable - just go into it with the knowledge up front you WILL BE hand loading for it and scrounging for components.
