Simply my take, but taking one of the most unforgiving propellants for handgun loads (Clays) + a very heavy bullet for this caliber that will need to be seated rather deeply = a bad combination... Not dangerous per se when used as directed, just not what I would choose if given a choice. This is especially true if you are a beginning reloader.
For me, anything faster than WW231 for most 9mm loads is a no-go, especially if I were to use a 147 grain bullet. Even in 9mm, when I see a min-to-max charge weight range of a half a grain for a certain propellant (700x), I get the heeby geebies, especially with a propellant like 700x that some people have trouble keeping within +/- .2 grains during normal reloading. I would go with something that has a slower pressure curve, i.e. AA5, Unique, HS-6, Herco...
