Lots of opinions so lots of offerings. I mostly use 3X9, 2X7, I would have no problem on the right rifle a 4X12X50 for elk, or more for varmit hunting. Western hunting where a 300-400 yd shot is taken would be routine with higher optics. Many of us need some additional eye help and thus higher scope power. Most of my eastern deer hunting is in the middle range 4-5 power.
