Your loads are hot. Both your loads are 100fps hotter than mine.
Too hot is the first things that stands out. It might also be that the bolt lugs are not all resting square against the barrel extensions lugs. That would mean only one lug is taking all the pressure. If this, then you need a new barrel.
I would drop your loads by 100fps and see how that goes before spending any money on the rest of the gun.
