You need to consider that burn rates can be considerably altered by a number of factors; case size, expansion ration, bullet weight, etc. so they are never a reliable method to determine substitutablity. Most burn rate charts you will find will specifically warn you not to use them to make powder substitutions or something to that effect.
If you really want to try Hybrid 100, I'd say call or email Hodgdon direct and ask if they have a recommendation and can give you a starting point.
