I've killed a LOT of deer with nearly that exact load, 9grs Unique and either the 429244 or 429421 from both rifles and pistols. Even wrote up a little article about it back in the '80's for SSK's HHI. Took a few bear with it too. And still use it today.
Out of more than a couple dozen deer that I've taken with this load the reactions can be as varied as one can imagine. From dropping in their tracks at the shot without a twitch to running a couple hundred yards before bedding down. Like us, deer are quite a lot different from one another. Two things that always remained consistant were that one, I never recovered a bullet from any angle. Always exited. And two, I never lost a deer shot with this load, nearly every one was a one shot kill.
