I load on a Dillon 550, so a rifle powder that meters like a ball powder is very interesting. I've seen Walkalong's results metering with his LNL and it looks good. Definitely would be nice not to hand trickle stick powder. They claim it is temp stable as well.
Anyway, the burn rate chart published at https://imrpowder.com/resources/data-sheets/ shows StaBall next to Hybrid 100V. StaBall is right in the middle of powders that are frequently used in .300WM and they publish data for .300WSM, so I wonder why not for .300WM (which I'm pretty sure outsells .300WSM by a considerable margin)?
