No negitive.
Never start that high with any load are any rifle.
Drop those loads down to 27 grains and slowly work your way up never increasing more then 3 tenths of a grain per step up.
What tools do you have?
I suggest a chronagrah, the hornady tools for measuring jump to land distances and grab a few of the diffrent load manuals including the 2 book set made specifically for the grendel.
Also if you can get ar-comp powder you may find it's temp stability over cfe223 to be much better.
