all my rifle scopes are 3-9x. with the exception of one Leupold VX-3 which is 3.5-10x.
i think it is a perfect magnification range. i grew up using an old 3-9 weaver on a 30,06 shooting long range jackrabbits. 300 yard stuff. first time i looked at a deer 200 yards away, i gasped..it was HUGE! i still have that 30.06 but a new Leupold VX2 sits on it.
my furthest shot was 250ish..i could go further with the 3-9 easy. big game is HUGE..heck the first word is "big".
at 3 power i hit a running coyote at 80 yards..
a rancher offered me $50 if i hit it.
