You will likely want to dial. What I do for my hunting rifle is figure out my MBPR and dial to that. Now anything inside that is just shoot it, if it's passed that distance take the time to dial the proper dope.
For windage as stated there is no sense in dialing for a wind gusting 5-20mph especially during hunting when you may be facing any direction. But if you are target shooting in a strong consistent wind say steady at 15 with gusts of 20mpg you can dial for 15mph wind and when you feel or see it pick up hold the difference.
The scopes I use have graduations beneath the windage turret numbered 0-4 on all 3 rifles the zero is on the 2 mark so I can remember that and always end up back at zero wind.
