The 6.5 CSS, at one time, could be ordered to be headspaced with either bolt, and you might still be able to do so, but from what I've read, the standard they use is now the Grendel bolt.
In a custom situation, I'm sure any of the chambers COULD be made to work with whatever bolt you want, but the .264 LBC, the 6.5 CSS, whatever Satern is calling their version of the chamber, and others are headspaced to fit the Grendel bolt as a rule.
from what I read on the .264 LBC is that it does not use a standard Grendel bolt, but would have to verify that with them as I don't have one to measure, maybe someone that has one could measure the bolt recess as a start to figure out if it is the same. I know on the ARP superbolt, shooting from the 7.62x39, he has never had to replace one for failure, according to what he wrote, again as Bill said 'internet wisdom' or whatever, just what he reported. On the CSS bolt, again only repeating what I read the and the reason I wrote 'should'. I'm far from an expert on the Grendel, I own two, both AA barrels, one complete upper from AA (which experienced a broken bolt with their ammo) and one I built. About to give the ARP setup a test and see how it does and see about OAL with the 1.5 degree throat and their superbolt, I believe it will allow for more accuracy from a button rifled barrel and less sensitive on loads as far as pressure is concerned from my experience and others posted on this site.
