Very interesting. I just put together an upper with the same JP barrel and head spaced bolt combo. Still waiting on an Aero Precision complete BCG for the 6.5 Grendel. So it hasn't been shot yet and no available factory rounds at the moment. Nor do I have any dies for it yet. Wondering if I should use the AP bolt and forego the JP bolt?
