i found some arisaka 7.7 ammo in a gun shop in my town would it be worth buying and reselling on EE?
Not unless you want to lose some money. Shipping will kill any notion of profit.
Arisakas got a bad rep, mostly through foolish propaganda given to the troops and public, during WWII.
Then of course, once the troops got to Japan and were picking up everything that looked like a weapon as a souvenier, they managed to find a bunch of training rifles with light, mild, cast iron receivers. Many of these rifles had worn out barrels installed, as well as damaged or worn bolts. It is rumored that some people tried to build them into sporting rifles and suffered from the effects of Kabooms.
I've seen and handled several of those "trainers" and in all honesty, I have no idea how anyone would consider them to be safe. Crude would be high praise for the pieces.
The tests that PO Ackley ran on Arisakas, was done with early and late model rifles. They were in good shape at best and from what I can get from the book, all were Type 38 receivers/barrels. He did some tests later on the Type 99 actions/barrels for strength as well but not in the initial tests for his article. Nothing changed in the later tests, He just couldn't persuade one of the actions to Kaboom.
He had some metalurgical tests ran on the steel and found the quality to be higher than anything any of the other comatant nations had been turning out, or from what I understand, any commercial manufacturer does to this day.
I did actually get to view and handle one of the receivers Ackley used in his tests. Ackley was a great guy, he took time off from a very busy shop to come out and talk to a young man that had read his articles in Canada and had taken the time to drop by his shop, just to say he had been there. I spent a couple of hours with him and we had lunch together. Fantastic fellow.
He didn't particularly like working on Arisaka actions because of their chambering system. He felt it was overly complicated but admitted it was probably the safest method for getting rid of gasses from case failures.
He unequivicably stated that the Arisaka, Type 99 and 38, were the strongest milsurp actions ever made for shoulder arms.
I honestly can't think of any better person to give a thumbs up on any action.
