Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Here is a picture of both from the 2017 Trophy show Along with the complete display. The only difference is 1 inch of buttstock.

Cool beans.
1. What is the correct bore diameter as made?
2. How "tight" is the chamber on your 6.5 Jap rifles?
3. Would you consider the Carcano/Jap rifles accurate?
4. What is the correct ZERO range for these rifles?
Thanks for your info and incite on the Type "I" rifles.

I just slugged the bore. It reads .267. The Medford rifling is very apparent. Bore is like new.

On the four of mine . Groove .265 to .266 . The chambers are very tight , so much so that a case fired in most T-38's will not resize enough to chamber freely in the Type I . I always use new brass and keep it for TI . All mine are very accurate .

Also none of mine have Medford type rifling . Maybe your bore is that large and shiny with weak rifling because someone polished it out . A friend just received a 1903 he bought with a ' bright bore ' . It was polished enough to have " Medford " rifling .

To tell you the truth I have never fired them at the range other than a function test. As far as I know the bore is standard Japanese spec. They are considered very accurate as far as I know, as good as any Type 38..

Since the Japanese used three different bore size and twist rates combinations , which one is "standard " ? Since the Japanese did use Medford type rifling and the Italians did not , How are they "standard Japanese " ? Each of the three different Japanese bore types shoot really different for me . The first type I can only get good results with .268 bullet , they tumble .263 boat tails . The middle type is so -so . The last type of bore shoots very well , but is not as common as the others . Which of these types does the Type I shoot " as good as " ?

The chamber in my rifle is very tight. I had to set the sizing die down to the shell holder with NEW brass in order to close the bolt on an empty case.
I have a supply of .268 round nose bullet,original and Hornandy but would like to find a Spitzer type bullet to try at long range. I'm not sure anyone makes a .267/8 Spitzer bullet for the Jap rifles.
I test fired a load into my bullet trap using IMR-4831 at 38 grains and it looks normal with no pressure signs.
The stock fittings are very easy to remove by hand alone and the barrel almost free-floats for the whole length of the stock. The rifle does not appear to have ever been issued.
Whom ever the other owner(s) may have been only fired the rifle a few times as the bolt face shown no wear at all from camming over on the cartridge head.
"FAT" is marked on the barrel at the receiver.

What .268 original bullets do you have ? The best shooting bullets in all my Type I's are regular .264 140's .

I think they are Dutch. I also have some .266 Italian RN as well.

I'll try some .264, but reports on the web at ranges past 100 yards were not good using .264.
