Advice about pressure signs

[lazyengineer]

Lazy,

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.

I haven't run QL, but I when I ran Gordon's, it worked fine in most calibers, but in 6.5 Grendel it was claiming common loads as way WAY over max. Maybe QL is better, but aside from freaking me out, I lost confidence in the modeling software when it comes to 6.5 Grendel. That said, you seem to run it a lot, so perhaps in your own experience you have more faith in QL matching your own observations?
