Most people don't realize that the .264 LBC-AR is a specific chamber Les Baer had made for him, while many chambers are unknown with ".264 LBC" stamped on the barrel.
As long as someone knew what they were doing when they designed the reamer, and the smith cut the chamber correctly, if the reamer was meant to feed factory ammo, it is usually fine.
There are some custom chamber variants meant for bolt guns or specific loads that may or may not digest certain factory offerings.
I personally just get barrels from reputable sources, and companies that back up their products 100%. I then verify each chamber as to what it will actually do, I don't care if it comes from AA, PF, Brownell's, Lilja, doesn't matter, I'm checking where my seating depths are, and if factory ammo will chamber fully, then extract with minimal effort.
