I had a very similar thing happen with Hornaday factory ammo and they were great about fixing the rifle and providing new ammo.
Pressures in the first fifty look fine to me.....number 51 looks a little hot.
I would have the firing pin bushed regardless. I noticed when you first posted the bolt pics that the pin hole had what looked like a taper around the hole. I have several 223 bolt face remingtons that do the same thing. primers flow back into that little taper even with light loads.
What about your rifle???
