I am finally back where this gun is located.
And pulled out my different ammo.
German Blue practice ammo, did what I expected. It was my test of ammo which should test that the firing pin works. It goes pop and the little plastic bullet hits the target. It doesn't have enough power to move an action. (If something was seriously wrong with firing pin or action or...it is the safest way to know.)
Remington worked just fine.
WinWhite Box works just fine.
Wolf steelworks just fine.
Norma, Fiocchi..Unreliable at times. I am guessing they are too powerful and the action is moving to the rear and coming forward too quickly. The bolt doesn't hit the rear of the cartridge. See Photo.
Seems consistent with both luger P08s.
