That's a pretty interesting looking sporter you have there!  As for loads, if you're worried about recoil, you might want to avoid lighter bullets (150 grain or less) and stick with 180 or 220 for game.  For shooting paper (which is all I do now), lighter loads are fine and I keep the charge well below max, so the kick isn't too bad.  I usually shoot 165 grain for paper.  165 would be great for medium game too... and the kick isn't too terrible either.
