If you are hunting big game 9x or 10x is plenty of magnification out to 500 yards,and I wouldn't have more than 3x for a minimum magnification.The high powered scopes are a handicap when a close range shot presents itself.A good 40mm scope is just as bright as a lower grade 50mm scope.On a limited budget the 3x9x40 elite 3200 is a good choice.If your budget is larger,it is hard to beat the zeiss 3x9x40 conquest.
