I understand.
Quickload.
26.5 AR Comp lists 56,700lbs at that load at 'mag length', which is 2.283" for a Grendel SS mag. Used the program's default case capacity 35.99gns of water.
QL outputs 2,518fps for a 20" barrel, which is as close to the OP's stated velocity as it gets.
Given velocity is a proxy for pressure I am very comfortable saying it is over SAAMI. Note, given the sensitivities regarding QL on the Forum lately I did not state the predicted pressure. I Just said that it is a hot load over SAAMI. Plus the ejector swipes which are also indicator that it is too hot.
My own experience confirms that the advice is sound.
