I have been hunting mn coyotes for the last 3 years I have called in several but the majority of my hunts are in a shotgun zone so most the time I watch them walk away due to them being out of range.
What kind of advice and where are you hunting? The fact that 90% of coyote hunters here simply beat the gravel roads with an electronic caller has made hunting them awfully hard. Coyotes get smart - fast Shoot me a PM and I'll share what I can.
I don't have any coyotes around my area any more. Its all wolves now. They must drive the coyotes out. Havent had a coyote on game cam in over 2 years. That is running 8 game cams too.
