There seem to be a number of interesting powders coming out on the market recently with different burn characteristics that I want to test out. You've now given me another one to test. I just have to figure out what to use to test it with. I don't have anything smaller than a .243 with a short barrel to use.
At least Hodgdon (owner of IMR) has data for it on their site. Alliant doesn't even list Reloader 23 and 26 as products for sale, even if they do have some load recipes they've worked. Those powders have me intrigued.
