The SAAMI spec reamer has plenty of clearance, it was designed to be extremely tolerant of bullet design, to the extent that many accuse it of being a machine gun chamber. The tolerance for the reamer is not specified within SAAMI only the minimum chamber size. The tolerance is the toolmakers descision.
The chamber is set to allow the guns to run excessively dirty and the carbon fouling deposits have clearance.
Hornady ammunition and the 123 Amax was designed for the Grendel chamber. Hornady is the SAAMI sponsor for the Grendel.
You have just found that you do not have a (correct) Grendel SAAMI chamber.
