You need 7.7x58mm Jap. If that is what you are looking at then yes, it will work. Hornady does make the proper round, as well as a few other companies. I would further suggest that you have the gun looked over by a knowledgable gunsmith befire firing.

 

Okay Thank you and trust me I will have this gun looked about more than once before I get behind the trigger. Its at least 80+ years old even though its an earlier made rifle unlike the "last ditch" later models the japanese made later in the war.

 

A big concern is not the strength of the rifle but making sure it has not been altered, as many were. When returning vets brought back those rifles by the ton, no 7.7 ammo was available, so many were rechambered, to .30-'06 or other calibers, some "wildcat" cartridges which were never factory made. Unaltered, it would be in 7.7x58 or "7.7 Jap".

Yeah I had a buddy who told me that since the ammo was so hard to find people would alter them to the 30 06 just to shoot them. To me thats just not right it destroys the guns history. I had no problem finding the 7.7x58mm i just bought two boxes from cabela's . I'm looking forward to if possible to shot this in honor of not only my grandfather but all those who fought in the pacific, such a great generation full of history.

 

The 99 was one of the first rifles to chrome line bores. Be sure to save your brass

 

My arisaka has a similar story

 

I have an early Type 39 long rifle--they are extremely accurate and my aging eyes love that peep sight an looong sight radius. Bought a box of Norma 7.7 Jap and took it to the range.Fired two shots at 25 yds just to see where it where it hit. First two shots were an inch and 1 1/2 inches low of dead center and split the vertical line. Moved the target to 100 yds, 2 and 2 1/2" low of dead center and split the vertical line. I put it away. Have fun!
