Slam-Fired Primer Dent Depth

Has anyone seen a slam fired case's primer whose dent is other than full depth the same as trigger fired ones?

The few dozen slam fired primers I've seen were dented the same depth as normal fired ones. Every rifle they came from had very little trigger creep before the sear released the firing pin mechanics. I suspect the shock of bolts slamming into battery disengaged the sear allowing normal firing pin function.

I have never seen a slam fire that wasn't caused by a stuck firing pin.

Interesting...... What rifle types?

All the M1, .M1A and and M14 slam fired empties I've seen were from rifles with free moving (not stuck hard in place) firing pins.
