    The very edge is not hit on my 10x XIII. It might effect extraction to change the rim, idk

    Folks are usually not talking about the rim exterior but the radius of the rim, which gets work hardened. I'd come in a bit from the edge.

    One thing to take into consideration is the angle on the outer edge of the firing pin tip. You are pushing a wedge shaped tip into the brass and deeper it goes the more it pushes brass out of the way, so if there is a big angle on that outside edge it can give you a false indication of how close the tip is to the edge is of the case.
