If you are not that concerned about max velocity try Varget. Varget is the go to for 6BR and the cases are similar in H20 capacity, the 6mm Grendel is closer to the 6BR than the 6PPC. I've been using the Berger 6BR data, starting with the start load and using QL to verify. So far so good and Varget works well.
