BTW I hope this one misguided experiment hasn't branded me as reckless. I'm starting to think that maybe it has. Oh well.
SD,
Not reckless at all - this calibre is relatively new and continues to inform as everyone shares experience. How will we ever know the limits if they don't fail. It could also have been a faulty part, but the load suggests otherwise.
Grendel is already a 223 on steroids and at the upper limit for what the AR15 will tolerate. Add to that experimenting with peak pressures and it is unforgiving.
You are not the only one who carries spares to the firing point.
