Anything from 180gr up to 300gr... with 240gr being the most common .44 Mag load. For deer, I'd look for a softpoint or hollowpoint in the 180-240 range... no need for bonded or hard-cast, unless you just prefer it. Hornady makes a neat flex-tip load... faster/more down-range energy... definitely worth taking a look at.
I'm still kicking myself for not picking up a new Win 94 in .44 Mag when I had the chance.
