When 6.5 Staball came out I asked the manufacture for load data for the Grendel. Below is their response that came today.
"thank you for reaching out to us.
The new Winchester STABALL powder is not compatible with the 6.5 Grendel. The burn rate of this powder is too slow for this cartridge. It is intended for cartridges like the 6.5 creedmoor.
