Distance, target size, and wind....F is spot on. Dialing rules, nothing can touch it, and marked reticles help with sliding for the wind.

That said, for less than 400 yards in hunting I'm really liking simple dots in a lightweight fixed scope. Not because hits are easier, but nothing moves and the need for all the advantages given by dialing isn't a major factor...shorter distance, large kill zone, less windage.

...but I'm still addicted to dialing.
