I recently acquired a arisaka rifle and not knowing much about these long guns, I took it to a local gunsmith who poured some gel into the chamber and once it hardened spec it out. He gave me a brief history on them and told me the caliber of this particular rifle was 6.5x50. So like a kid with a new toy, I can’t wait to field test it but first it’s off to the sport shop I go for a box of ammo. Strangely enough, no one at the sport shop had ever heard of a 6.5x50. Only 6.5x55, 6.5 Swedish, etc. So I decided to research this myself as much as possible online but end up more confused than what I started. On a few forums that I came across one guy says that the 6.5x50 is the same as 6.5 Jap. Sounds likely to me, after all, arisaka is Japanese. Another states that a standard .264 win is the same and yet another fellow claims that it’s a .256 cal. Anyone have any thoughts on the subject.

That ain't surprising. Sporting good stores don't have the most knowledgeable clerks at the gun counter..... ;)

But 6.5 Japanese is what your gun should fire. You can find it at ammo websites and maybe a local gun show. There is also a 7.5 Japanese, they're not the same. One chambered for one can't fire the other.

Many firearms have cartridges that go by different names but are actually the same. The 6.5 Jap is the same as the 6.5x50. The 6.5 is bullet diameter and the 50 is case lenght both in millameters. Bullet diameter in inches is .263 to .264". Hope this helps

I too own an araskia rifle. Mine is a differnet caliber. But close. The 6.5x50mm is the 6.5jap. It is not however s 264 win mag that is close to a 300 win mag necked down to 6.5mm bullet great cartridge but not yours. and no the 256 is not youras either.

You can order ammo from I believe.

They are not the most accurate rifles out there but they are strong. Seen a test where a guy packed so much Bullseye powder into the case that it was starting to push the bullet out. It took some wacks with a hammer to get the bolt open but the action was all intact. Now that is TOUGH. mine shoots 1.5" groups at 100 yards on a good day most days it is 2 to 2.5" with peep sights (That I really hate).

I have rebarreled Arisaka 38. The barrel is heavy with thight chamber cal. 308Win. It is now very accurate rifle. The scope mount is Redfield mod. "Remington 788" I think.

Just a word about the Arasaka Type 38 rifle. They have a very liberal chamber dimension. The possibility is highly likely that when you fire a round and eject the empty you will notice that the empty will have a slight bulge in it near the case head. After a lot of research with fellow mil-surp collectors specializing in the Arasaka I found that they almost all do that and it is normal. If you handload simply neck size only as working the brass back and forth to spec will weaken the brass and you won't get a lot or reloads out of it. They are fun to shoot. Good luck!

I have two 6.5 and they dont bulge the cases.Hornady and Norma make the rds.
That is 7.7 X 58 or 303 cal not case..312.I have 5 of those.I have found that 7.7 norma bulges,no doubt they use 8 mm cases.I make 6.5 from 35 rem but grafs has 6.5 new cases.Privi Partisian brand. :rolleyes:

"Another states that a standard .264 win is the same"

That's great, but quite harmless error. You couldn't get a "standard .264 Win." to enter the chamber!

The Japs sorta shot themselves in the foot with their small arms ammunition. They had so many rifle cartridges the troops in combat often found themselves with lots of ammo for guns they didn't have!

Not only is that Jap 6.5x50 ammo going to be hard to find, if it's possible at all, even finding reloading dies for it will be difficult. You likely have a wall-hanger.

I also have a 6.5 jap. It's a nice shooter, but the problem I face is if you don't reload your own, the price for 20 rds can be expensive. I saw some at a gun show, $30 bucks for 20. I left it there.
