If you are calling, IMO, 6x is too much. I missed some opportunities when the coyotes came in from unexpected directions and were so close I could not find them and aim properly when I had a 6x. Unfortunately, they used terrain to get away before I could find them. Field of view can be too small.
I use a 2.5-8x36 for my calling rifle. I keep it at about 4x. I seldom turn it up except at the range testing loads or sighting in. I shoot out to 450 without cranking the scope up.
