Mike,
I can't tell if the firing pin that came in the rifle was original or newly made. It was slightly bent and certainly didn't work. I made a several new firing pins of variating lengths and one with a retracting spring. When the firing pin was short enough to allow the action to function, it wouldn't reliability fire the primer. Likewise a floating firing pin appears to be to light to properly function.
Do you think that the original design had no provision for independent firing pin retraction before the breach block began to rotate?
