Like most experienced hunters I've been surprised up close more often than at longer ranges so I try to keep magnification low while moving or in heavy cover. The Z600 & 800 reticles on my hunting scopes require maximum magnification to be properly calibrated so longer than 350 yards I'm at maximum magnification either 9 or 15. Sitting on a side hill watching I'm inclined to use 5-6 power for easier identification of legal or not.
