Odd thing happened to me yesterday, and luckily did not involve any personal or material damage.
A number of years ago my, now deceased, uncle gave me a rifle he had been given by his uncle. The rifle is a Type 99 Arisaka, from the Nagoya Arsenal. It was missing a lot of the issue parts and I spent time getting the missing parts of the sights replaced, and a original dust cover, Nagoya bayonet, etc. Parts dealers who looked at the rifle said it was no big deal, nothing special. Just a 7.7 bring back with the chrysanthemum ground off. So not a battle field pick up, very little value other than the intrinsic value to me as an inheritance.
Problem came this weekend when I took it out to shoot if for the first time with a box of Norma 7.7 ammo. I checked to see if the bullet would fit into the muzzle end, to make sure it was not a 6mm rifle, and it looked dead on.
Loaded the internal mag with 5 rounds, chambered and shot the first round. Round went almost exactly where I had intended, and was happy with the light recoil and feel of the gun. First indication of a problem was when I had to repeatably beat the bolt back with my palm to get the round to extract. Another shooter looked for signs of overpressure and inspected the case, primer pocket fine, but the neck and shoulder of the round was blown out.
The chamber seems longer than that of the 7.7 Norma I was using. Took a round off, and it fell into the chamber and could not be picked up by the extractor. Had to use a cleaning rod to knock it back out.
Talking to my cousin later, he stated that he thought the rifle was a 7mm Mauser from boxes of old rounds left behind by his dad. Of course I never heard of this before last evening. The barrel is original, and not sleeved.
Questions, Was that a common conversion after the war? What is the best and cheapest way to determine what chamber I have? Why would it be re chambered for the 7 Mauser, when it might be closer in size to the 8mm Mauser which was common after the war?
Thanks for your thoughts.
