I think it only matters to the "box stores" of the world, and lawyers. Custom makers have been chambering many variations of many chamberings for years. In your example, everybody who has been selling either 6.5 Grendel, .264 LBC, etc., would not be doing so right now. So, for those besides the box stores and some ammo makers, it changes nothing really except they are now able to use the Grendel name I assume. For the marketplace, it does open up a lot more ammo, gun manufacturers, and lawyered up stores to carrying the Grendel, which is a good thing for everybody. I could be wrong, but I believe SAMMI only specifies demensions and pressures which ammo and chambers are to be spec'd at, it does not certify that a manufacturer is actually making them to spec or out of material that would deem it safe, so there is no SAMMI "cerfitied safe" ammo or gun.
