I'm wondering if the bolt face is maybe a little thin around the pin hole and they don't exhibit this until a few rounds have been fired? That might explain why they are not seen until the gun has been fired a few more rounds than it would get in inspection and the Maryland spent casing test, if that gets done to this model. Mine was purchased used from a local Range Officer's trade in for a shiny Kimber. It has had a good breaking in period by him and I have not noticed the primers looking like this.

I do look at my brass at each shooting session and I haven't seen this yet.
