1) yes it was, as was already replied to.
2) Not "probably", not "slightly". You are well more than "slightly" over 60,000 psi. 100 fps over SAAMI MAP is going to come at a price of 6-10,000 psi. And so back to the point, equal over pressure before claiming anything. 260 has more capacity, but isn't efficient enough to do anything with it at normal pressures.

So again, if they start out the same; then over-load then the same. There are plenty of people running the Creedmoor that hard as well, isn't difficult if not shearing lugs is your only requirement...

I've posted enough pressure data, and specifically around this cartridge to show that several times.
