Rodell,
I've never seen a 3-9x 3-10x with enough parallax at 200 yards to make any difference on big game, and usually there's none. I have, however, seen a few with maybe 3" of parallax at 300 yards, but that's rare. The best thing is to test any of your scopes at longer ranges for parallax if it's a concern.
Most scopes up to 10x don't have parallax adjustments, because it's such a minor factor n big game scopes up to that magnification.
