Pap, I use an OLT rabbit distress call and a squirrel distress call. No electronic stuff.
State forest regs prohibit any caliber larger than 22 mag in rifles and for shotguns no slugs or shot larger than #2.
My go to for the coyotes is a 16 ga Stevens single shot rescued from a dumpster many years ago. Shot size that I use is #4 and with the modified (shortened bbl) and other upgrades I gave it, it is really light.
Touch off a round and you know something "had occurred" Patterns quite tight out to 40 yards.
