Anyone hear of Grendel II using a 6.5x47 Laupa throat?

Am I missing something here? I can see how a longer reamer can make a shorter throat, but how does a reamer larger in diameter make a tighter chamber?

You're absolutely right. I guess that's what happens when I post at 12:20 a.m.

-.001" reamer allowance means smaller chamber than SAAMI allows, since SAAMI only allows .002" on their chamber drawing.
