I'm going to be working up a .300 Win load for long range deer myself. I just bought a box of 180-grain Accubonds (the 200s just weren't sufficiently accurate in my rifle, but 180-grain Hornadys were superb, leading me to believe that my rifle doesn't like the heavier bullets).
The truth is that even the plain old 180-grain Hornady flatbase (which, as mentioned above, shoots beautifully in my rifle) will do the job on deer at any sane range (like inside 500 yards). A premium like the Interbond or Accubond is probably not needed on deer, but I like the plastic tip because it guarantees expansion, and the fact that these bullets are bonded gives a little more comfort when impact velocities get higher (as they do in the .300 Winchester Magnum at close range).
Either the 168 or 180-grain Barnes Tripleshock would also be truly outstanding, and would work on any big game animal in North America at any sane range.
