[QUOTE="entoptics, post: 2668567, member: 104268"] Not from my understanding. The belt can only keep the case from going [I]forward[/I] into the chamber, and the bolt face doesn't "crush fit" the brass against the belt, so there's some amount of wiggle room. If I'm reading the SAAMI drawings correctly, it looks like the measurement for the cartridge is 0.220" base to belt with a -0.008" tolerance, and 0.220" - 0.227" for the chamber. That could potentially set up a maximum headspace (short belt, long chamber) of 0.015", though such extreme tolerance stacking should hopefully be rare. [/QUOTE]
