I have a .303 British Enfield whose bore actually measures .316. I have fought the rifle for years trying to get a store bought bullet to shoot accurately. I am now ready to give in and try a .316 bullet but of course I haven't been able to find any. Can anyone tell me if there is any such thing? I am only interested in jacketed bullets since I want to use the rifle at full power. It is a WWII rifle and is strong enough shoot along with a .308 Winchester.
