Just remember you're using 2 different shaped bullets, so the bullet seating die will need to be altered, depending on which bullet you're leading.
ADI have some reloading info on their website, where you can find your calibre/bullet/powder combo.
They don't seem to mind if you print off the page you want.
Usual precautions/let outs apply.
