50 V-max (53 and 55 great too) or 69SMK.
For coyotes, minium 3-9x40mm for me, prefer 4-12x, 4-16x, 4.5-14x, 2.5-16x, etc.
Here's why: the entire ribcage on a coyote is smaller than the lung of a whitetail deer, and the vital zone is under 1/4 the size. So a vital zone on a coyote is about the same size at 100yrds as that of a whitetail at 400!
1-6x will work, but more magnification is worth the weight.
What barrel length are you shooting?
