I'm confused about why it would matter if it's a SAMMI chamber or not (for the purpose of the last two posts, I realize the implication in the market of it being SAAMI approved)? THe .264LBC chamber is compatable with 6.5 Grendel Ammo. There are a lot of variations of many chambers for many cartridges that are being chambered right now. How many .308 reamer demensions do you think there are? A lot of custom makers tweak chamber specs for customer rifles, but they are still safe to fire SAMMI spec ammo. It really doesn't change anything that I am aware of for a custom maker, except now maybe he could call it a 6.5 Grendel "Tight Neck", or "Match", or whatever instead of coming up with a name that doesn't violate a copyright.
