Dave..........You are on the right track, and will easily be set up for 99% of all calling situations. If you can get a 1 x 4 with some heavy crosshairs that don't get lost in the brush and foliage all the better. To have parallax set at 50 or 75 yards is acutally a bonus, as most your shooting of called coyote will occur at theses ranges.
You may see a fuzzy shadow of your barrel below 2.5 magnification, but is not distracting, and clean shots are easily made.
Dont get hung up on big power, as I did a survey in the spring here, and the average shot on a coyote with every respondant averaged out to 75 yards. Even open country fellas shot alot of coyotes close.
Very few shot over 150 yards which is an easy shot with a 4x scope.
