Just got this Type 99 Arisaka, today!
Great condition, no mum (some is barely visible), I think it has a chrome lined barrel, and 20 rounds of ammo.
Got it and the ammo for $180.

Yeah, I think having them reloaded would be the best option. I can that the ones I got, have already been reloaded. I don't know how long the cases last.

Do all the numbers match? Do you know the arsenal and series?
There were 3 main variations of the T99 short rifle, early ones had the chrome lined barrel, AA-sights, Monopod, Dust cover, The next or "Simplified" T99's were made with earlier parts, but the unimportant parts were left off, only some have chrome barrels, AA-sights, they used up what they had before moving to the "Substitute" T99 or the "Last Ditch" series of rifles.. I cant tell from the pics if its a early one or a "Simplified" one...

If you want info on the markings, heres a great site: http://www.radix.net/~bbrown/japanese_markings.html

The 7.7 Jap is based on the .303 Enfield Ctg. The .303 brass had the rim removed for rifles and a partial removal for the Hotchkiss MGs. There are 2 types of the 7.7 one rifles one for MGs. They can be made from 06 brass but the 06 base is too small to chamber in the 7.7. They are stressed out pretty fast in the Jap rifle. If you have a lathe you can turn down the .303 Brit and make the cases. The best way is just buy the loaded ammo to get brass.

:confused: All I shoot out of mine is cut down military '06, it doesnt bulge and works just fine.
The actual 7.7 brass I have I treat like gold, and havent reloaded it yet.

The 7.7 Mg ammo was a copy of the .303, not the rifle round, it 2 mm longer without a rim..

Japan produced a number of machine guns that were direct copies of the British Lewis (Japanese Type 92 machine gun) and Vickers machine guns including the ammunition. These were primarily used in Navy aircraft. The 7.7mm cartridge used by the Japanese versions of the British guns is a direct copy of the .303 British (7.7x56R) rimmed cartridge and is distinctly different from the 7.7x58mm Arisaka rimless and 7.7x58mm Type 92 semi-rimmed cartridges used in other Japanese machine guns and rifles.

For the rifle you turn the complete rim off the .303. The machine gun has a semi-rim. The question is was the partial rim left on the MG round for extraction. Or was the rim left to keep it from firing in the rifle?

The only thing the .303 British & the 7.7x58 Arisaka have in common is the bullet, you can make cases from the 06 Springfield & the 57 Mauser............

The 7.7 is based on the .303 Brit. both case and bullet. Yes you can use an 06 case but it does not change the history. The JIS metrics used in Japan were taken from the English standards as were most industrial processes at the turn of the 20th century. The Japanese supplied Arisaki rifles to the British Army during WWI. The turning of the rim on the .303 for use in their own weapons was easy.:)

Then why is the 7.7 case 2mm longer?

The case is based on the .303 Brit. There was a always a problem with engineering when Japan modified the British Metrics to the Japanese Metric Standard or JIS which differs from the Komotsu Metrics. It is not enough to worry about. The English had a problem making ammo to fit the Arisaki rifles they used due to these differences.:)
