Having had both, I found that the 264 LBC, (I've had 2 different barrels, one of them a Lilja) is simply pickier to load for. The LBC's tend to like longer bullets, but I did find a blazer load with a 107 Sierra.
I can load most bullets to mag length in the SAAMI chamber, and almost every bullet between 95 grains and 129 grains (thats the heaviest I've shot) will go under 1 MOA.
There is nothing wrong with the LBC chamber, just think of it as a tighter, more bench rest type chamber that requires a little more work to find the best load. I like working up loads, so I have no issues with that.
Many shooters are new to AR type accurate rifles, and most of us want them to have as easy a time as possible when they try to shoot the tiny groups the Grendel is capable of. The SAAMI chamber seems to make that more possible earlier in their experience.
When I started shooting the Grendel years ago, 6.5 bullets that were in the weight range were tough to come by, so I loaded everything I could find between 85 and 129 grains. Most shot well. At one point, with my first Grendel, I shot every factory load available into groups that were sub MOA. (Well, except for Wolf Soft points, which were crappy).
I actually don't want that chamber in a bolt gun, because I think that you probably need a deeper throat to get the absolute most out of what a bolt gun can do, and I would load especially for it, but others feel differently, and I'll buy whatever ends up being built and change barrels if I can't get what I want out of what comes standard.

You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
