I don't know squat about factory loads, but whatever you use here in the states for deer will be just fine, assuming you hit them right the first time.
For scopes, I use nothing but fixed 6X, plus a few random 4X for good measure. I did borrow my pH's rifle in the Limpopo though, but never took the variable he had off of 3X or maybe 4X...can't quit remember.
One thing I should add: bring half the cloths and twice the money you were planning to...
