CZ 527 6.5 grendel CFE 223 chrony data.

With those velocities you will be super sonic well past 1k at your your elevation. You can run your load through a ballistic program line JBM or Hornady Ballistics calculator and find out. Being able to seat longer and having a 27 inch barrel will increase speed over what most of us get. Nice build
