The pressures will go up dramatically when you reduce the neck size and you are reducing the neck size significantly if you go from a 6.8 or .30 caliber down to a 6.5.
If you can't find this powder listed in any of the numerous loading manuals for the Grendel, you best stay away from it.

Hornady and Nosler both have published data for their 100gr bullets with 10X.
Pretty sure they would not publish load data if it was indeed "Dangerous".
