Since you won't be able to control conditions each time you go out, a heavier projectile stays more "true". That is, bucks the wind better, different humidity, etc.
Work up the most accurate load for the heaviest caliber you feel like handling and go for it. Book learning and ballistic tables can give you a pretty good idea what to expect but only putting holes in targets proves anything.
