UPDATE: Prior to completely assembling everything, I just
put the firing pin assembly in the bolt. Under magnification
I observed the mating surfaces of the sear nose and cocking
cam. The sear nose does not make full contact with the cam.
In fact, it barely touches (.010"?) For it to make full
contact, metal would have to be taken away toward the O.D.
of the bolt. That would increase the angle toward the top of the
cam, which may or may not make the bolt hard to lift just prior
to the nose cocking at the top of the stroke.
What to do? If I do that, there is no turning back!
Stop dry firing it. If you have to fire it to check after polishing the cocking cam...use a brass w/a primer in it. powdr
My Dad bought this rifle in the '60's at a time when it was
considered voo-doo to dry fire ANY rifle. He never dry fired
it, nor have I. I doubt if it was ever dry fired, even by
accident.
