I used to use a lot of 3x9 scopes and such for called coyotes. Usually kept the scope set at 3 to 4 power. Now I mostly use fixed 6 powers and a few 1-4x scopes. I rarely shoot past 200 yards.
Pretty much my experience as well.When I was doing more calling the fave set-up was a Sporter weight .22-250 with a fixed 6X on it. A " Set it and forget it" kind of rig...with a 200 yard zero if they showed up anyplace inside ludicrous distance you just point and shoot.
