To compare a 1944 or 1945 Arisaka with a Springfield 1903A3 is a laugh riot.
Yes it is, in regards to laughing at the Springfield. Considering the Jap rifle has a gas escape system that is light years more advanced than the crummy almost non-existant protection you get from the 03a3.
As a matter of fact people in my area have for years have been making 7.7 jap cartridge cases out of 30-06 cases. Not recommended because of the 06 case is smaller in diameter at the base but to date after years and years of many people doing this no one I know ever got hurt when they blew a case because of a super hot overload. The Jap action is actually that strong and well designed to protect you from escaping gases.. Don't think you would not get hurt if the same thing happened with the 03a3 Springfield.
Maybe very late guns were indeed made of substandard steel but the regular runs of 7.7 Ariskakas I have seen , owned and shot were made of steel not iron. P.O. Ackley who forgot more than you will ever know stated that the steel was slightly inferior to other bolt actions rifles but the design was so superior to most of the other bolt action military rifles that it made the gun damn near indestructable. That makes the grade in my opinion and I have never had any trouble with my 7.7 Arisaka even when using reformed cases from '06 brass. I would never even contemplate doing something like this with an '03 Springfield rifle or British Enfield if smaller in diameter and plentiful such cases existed ..
The 03a3 Springfields were made with a lot of cheesy stamped parts and all hand undersize bolts to speed up the manufactures production and fitting of the bolt to the rifle. They certainly were no works of art but it is only the Jap guns that often in the past got the scorn thrown at them and the majority of the 7.7 guns (except very late war ones) had light years better fitting and workmanship and in my humble opinion shot a might better too. And the 7.7 Jap guns did not have hurry up 2 groove barrels either.
As a matter of fact some Springfields I have seen actually had the gas esape hole drilled on the opposite side of the receiver in relation to the gas escape hole in the bolt. Now that was really a genius of an engineering feat. One wonders if the people that didi this were on drugs that came up with that idea.
You stepped right into the do, do, on this one Mike there is no Comparison when talking of the Jap 6.5's and even the large majority of the 7.7 Arisaka's. The Arisaka was the superior rifle military rifle in all respects.
Even the famed 98 German Mauser rifle was not as strong as the Arisaka's and it too deteriorated in workmanship as the War came to an end. The only differnece between the German 98 and the 7.7 Jap and the Springfield was that the 03a3 Springfields workmanship was bad right from the beginning of production during the war and our factories were not bombed to smithereens and our raw materiels cut off.
