Jap model 38 Arisaka action
What is the 6.5 x 50mm Jap action called ? A small ring Mauser (1") ? or is it in itself ? Trying to buy a rifle barrel to fit , not much luck. Where can you get a barrel re-lined ? Midway does not sell a barrel for the Jap action / thanks

It is unique to itself. It is just what you said, a Jap model 38 Arisaka action.
You won't likely find an aftermarket barrel for it that is prethreaded; you can get a blank and have it cut to fit the receiver though.
Unless you have a lathe and the know how to do it yourself, you'll end up sinking several hundred dollars in parts and gunsmith fees into a rifle that at the end might be worth $200. Not really worth it.
You wouldn't get the barrel re-lined, but you could get it re-bored. That service in and of itself costs several hundred dollars. If you DID go that route, 7mm mauser would be a good choice as the Japanese made mexican contract arisakas using the same pattern stuff as their own guns used, and boring out .02" of bore would be deep enough to remove the original rifling but not so deep as to think out the barrel much. But again, not really worth it.0 -
The Japanese Type 38 has a odd barrel shank size, i.e. 14 "V" threads per inch, with a O.D. of 1.020" X a shoulder length of .720. Your going to have to have a smith cut it for you on a lathe with a single point tool. 0 -
Jap action are safety breeched. That is, the barrel is recessed 1/2" or so for the bolt nose to be enclosed ,adding expense to a rebarreling job.
It's a rough foundation to build a rifle on and you will have more money into it than it's worth.
Dillon 's Blue Press wrote an article on how great these actions are
but don't believe it, it's a myth and the guns are JUNK.0 -

Well, according to independent post-war testing by both the NRA and the US Military, the Japanese Arisaka had the strongest action of any nation's war-issue rifle.
The gun is certainly intrinsically tough enough to rebarrel into various more powerful calibers.
But as mentioned, the nature of the beast is such that its just not cost-effective to rebarrel these guns. The complicated breech that makes the gun so strong also makes it complicated to work on.
Further, doing so not only destroys any (limited) collectors' value of the gun, its also likely to be more expensive than just buying an entirely new gun.
If the action is already barreled, and you need something different, the "best" option may be just to have it rechambered to accept another 6.5mm round.
Good previous thread on this here:

In the mid 1950s I repeatedly set back bolts,allowing the 1.951 gage to enter,in arsenal converted Jap 30-06s. Ammo used was M1 Ball. Over 500 rounds did it.
These were beautifully done military arsenal conversions with polished bolt faces.
Initial headspace was uniform such that bolts could interchange between rifles.
You can quote anyone you want but them are the fax, Jax.
The guns didn't blow up but bolts suffered surface failure and headspace crept up just as a Springfield will with proof loads.
The Jap rifle was designed for about 43,000psi working pressure and will take plenty more but not holding the same headspace.0 -
Wouldn't trade my Flaig's converted Arisaka for anything, but then, like the man said, if I had to sell it, $200 might be strong money.
Saw a bench rest .308 once that someone must have sunk $500 into the stock alone; bull barrel, nice glass. Was selling for about half of what a good Mauser with the same treatment would have gone for.
Won't get into the post war strength test issue. Wasn't there, but I did tie one to a tree once, hid behind a second tree and pulled the trigger with a string. Someone had tried to chamber the wrong round in it and the bolt wouldn't open. I'll never know what that round was (chambering was .308. When it went off the primer pocket doubled in size and brass had filled crevices I didn't know the action had. No hint of any headstamp. Checked headspace and it was fine. No damage to the action.0
