Hodgdon does list it with the heavier weight bullets in their data, I think it can work and work ok but max loads are compressed and I think you might find a good load for it but might be giving up a bit of speed especially with lighter weight bullets. Burn rate IIRC for Staball is close to H4350 and that would seem better for the cases with a bit more case volume. But if you have it give it a try and let us know.
I could be wrong but I think it might be a case of diminishing returns especially with the lighter weight bullets, which I have seen a few times for cartridges and slower burn rate powders. I suspect it will not get good burn without being near the high end of charge weights and that is something I shy away from with the AR platform generally. Keep up with velocity in the ladder test and look for plateau of velocity as powder charges increase. I think with the lighter weight bullets you might run into that.
Like I said earlier if you have it give it a try and let us know. Curious to see the data. People did say CFE223 and Leverevolution were to slow for the Grendel and they work fine.
