    An additional point of concern in the design is the inertial firing pin. A lightweight firing pin rides in a channel inside the bolt unrestrained. When the bolt locks forward during loading, the firing pin typically rides forward and impacts the chambered round's primer. In military specification ammunition and quality civilian ammunition, this is not normally enough to fire the round and only leaves a small "ding" on the primer. With more sensitive primers or improperly seated primers, this can cause a slamfire during loading.

    So long as you don't just let the pin slam shut there would be no problem ever right???? I mean you can just ease the bolt shut right???

    wel not really, as the bolt goes forward, the center part rotates and locks in, thats what they train you to slam it foward, however
    there is a forward assist, you could close the bolt slow, and "assist" it forward for a silent chambering of a round

    As a school trained armorer in the Army, I have never heard of the firing pin dimpling a primer, when the bolt is released to go forward.

    I have been witness to a couple of "cook-offs", and they are scary as hell.

    I would be more inclined to suspect a headspace problem, if you get a discharge when releasing the bolt. A primer that is not seated all the way could also discharge. I have only seen that on reloads with poorly cleaned cases.

    yes, in theory, you could lightly hit the primer, and it would barley sizzle, and then light off the round, or damp powder in the round could cause it to slowly light off.
