The Les Baer chamber is called the .264 LBC-AR, whereas a lot of variant chambers are called .264 LBC by the particular barrel maker. There's a chapter on it and other chamber variants in the 6.5 Grendel Volume I Reloading Handbook, which basically emphasizes that you need to load for your chamber.
Sorry, I meant chamber and not cartridge. What I mean though, does the LBC bolt have the same dimensions as the AA bolt? My Lilja barrel will have the 6.5 Grendel chamber headspaced to an LBC bolt, but I would think because I have the correct chamber, that an AA or MF bolt would work just as well.
