Relative burn rates from fastest to slowest (issued by Hodgdon/IMR) Nov 2019

I honestly can't answer that one. You could call Hodgdon and ask. But if you use it, I would buy up what you can find because there won't be anymore once it's gone. Superformance is probably pretty close I would imagine, but I haven't used it.
