Arisaka Action Threading

Hey Guys,

I have a 25-06 that was made about 20 years ago. It is made on an Arisaka action. I was told by a gunsmith, not the gunsmith that built the rifle, that the barrel was being held on by only 2 to 21/2 threads.

Is this safe?

Thanks a bunch,

Smoker*

And just how did he determine this? The Arasaka is very similar to a Mauser, and a rebarral would have been required to get it to .257

Sound like someone didn't know what they were talking about. The Arisaka threads are about 14 TPI.

Hey Tailgunner & D Humbarger,

I was shooting some really hot loads - really hot and I guess I did something to the action. The 2nd gunsmith I took the rifle to set the barrel back about an inch. He said that I shouldn't shoot charges any hotter than .257 Roberts.

He also said that it looked like whomever put the barrel on used something like "lock tite".

Sounds like both of you may be correct. I'm not a gunsmith and I don't know what the threading looked like when he started. I don't remember why the 2nd gunsmith said he had to set the barrel back.

He was the gunsmith that said there are only 2 - 21/2 threads left.

That's the complete story.

Thanks guys,

Smoker*

OK, You pounded the lugs back into the receiver, damaging (probably) both the bolt and the receiver itself. If thats the case, I'm surprised that he didn't recogmend scrapping the whole thing. Just guessing here, but it sounds like you need a 3rd gunsmith (referee).
I'm betting that #2, after recutting the lug seats past the case hardened surface and possiably working over the bolt lugs themselves, simply cutoff most of the origional threads, and undercut from the last of the origional thread to the new shoulder (instead of picking up and contuining the origional threads back to the new shoulder).
While I question his repair methiod, the blame for the origional dammage lays squarly on the shoulders of the guy that was shooting "Really hot loads".

Smoker--You need new set of threads;If the smith that set barrel back did
so by cutting barrel shoulder ahead, without extending threads to the newer shoulder.Two ways to do it.Either cut old threaded area from barrel and redo it or get another barrel.Arisakas are super strong actions, but things still have to be done right.Ed.

That explains the thjread lose. [Roll Eyes] If you insist on shooting that Arisaka rebarrel that thing to be on the safe side.

Hey Tailgunner, hubel458 & D Humbarger,

If I damaged the lugs and reciever the fault is mine. When this had occured the Internet hadn't been invented. Qualtiy, reloading help was hard to find. I no longer prepare hot loads. At least not this hot!

I'm taking the rifle to my gunsmith as soon as I get over that way. Maybe a couple weeks. I haven't shot the rifle for at least 10 years. (I have a few other rifles.)

If the gunsmith says that I should not shoot the rifle or use reduced loads, I'll lead the barrel and us it as a wall hanger. I don't want to trash the rifle because it was my first custom rifle.

I appreciate the input from all of you. You've given me good information for which I am grateful.

Thanks again guys,

Smoker*
