What is the best coyote hunting rifle?

if you are wanting to hunt coyotes at a far distance and still have knock down power i would go with a 55 grain .22-250 or a 55 grain .223 or a 75 grain .243. Those are the bolt actions tho. if you wana go with a semi auto i would recommend a bushmaster AR-15 in a .223 round 55 grain or a bushmaster AR-25 in a .308 130 grain .243 75 grain or 7mm-08. But a AR-15 will run about 1000 dollars and a AR-25 will run bout 1500 dollars. i would go with a AR-15 with a 4x12x60 scope. If you want the best of the rimfire caliber for coyote and varmint, there is the new from this year, the .17 Winchester Super Magnum (WSM) 20 gr bullet at over 3000 ft/s Centerfire like performance at a rimfire price.
