I have one, there is no "most accurate" load. Each gun varies, you'll need to try them out in your own rifle.
I prefer 180-grain loads, and mine with an aperture sight is a fairly consistent 2-3 inch shooter at 100 yards with different makes.
You obviously wouldn't need a heavy bullet for whitetails, but it'd still be a matter of trying a couple & seeing what they do with your gun.
Every rifle has its own personality.
