Nikon BuckMaster with BDC Riflescope Zeroing ?

Is it a good idea on Nikon Rifle scope with BDC to unscrew the elev.& windage screws without moving the turrets & bring those turrets dials back to "0" by lifting it up and tighten it back after zeroing at 100 yds so that u can play those turrets for long range elevation & Windage correction ?? Need your view on this matter...thanks.
