I don't know about specifically, but I have heard, read, and used it as THE powder for .30 M1 Carbine loads....
Bruce Hogdgon sold the military WC820 pulldown powder and marketed it as H110.
I picked up this item from the CMP Carbine Notes published somewhere on their website. It makes sense since Winchester developed both the rifle and the cartridge from the ground up and would have needed ammunition for the prototype testing. Kinda moot point now, since WW296 and H110 have morphed into exactly the same thing.
I stand corrected, if it was indeed created for the military round…..
