Well, I finally brought the 7.7 jap rifle back to Indiana from my dad's house this weekend. The gun is in pretty good shape cosmetically on the outside, but the bore is MINT!!!! I ran a boresnake through it today at lunch and it is bright and shiny with crisp rifling!!
I can not find headspace gauges for the 7.7 jap so I am thinking about buying a box of the Norma ammo and clamping the gun to a shooting bench and firing a couple of rounds with a string attached to the trigger and then measuring the fired cases and comparing with pre-fired measurements.
How do I go about giving this gun a thorough pre-firing cleaning?
The numbers on the bolt match the receiver, but there seems to be some slop in the action when I work the bolt. Also, when I close the bolt it slides forward easily and then I have to put a good bit of pressure to close the bolt the last one half of an inch. It feels like a spring is compressing in the last half inch. Is this normal?
Also, when I dry fire the gun (I know that I shouldn't be doing that, but it has been dry fired hundreds of times by my dad when he was a boy 40 some years ago) the bolt seems to rotate open just a hair. It doesn't rotate ope by any means, but moves visibly when dry fired. Is this a worry?
Any help that fellow 7.7 Jap and other military rifle owners have would be very welcome and much appreciated.
Thanks in Advance,
