Not quite. Hornday uses a different blend for different cartridges--and they don't sell several different Superformance or LeveRevolution blends to handloaders.
My point exactly SU35, btw, I don't mean this in a cocky manner whatsoever, I was just saying if it was the same stuff, it would work for a lot more cartridges, but one powder must not be able to cover everything, it would be cool if they released all of the different blends. Also, I'm glad it works well in your 300 WSM, hopefully it will do well in my 300 SAUM also.
