I must be lucky - the two Ranch Rifles I have owned have been acceptably accurate for 150 yard coyotes. My new one, a retooled 580 series, is more accurate than my older one and shoots to about 2 - 2/12 inches at 100 yards. Not near as accurate as my sub-MOA Sako .223 bolt gun, but good enough for a rough and tumble truck/farm gun. I like mine because I can carry it in my truck uncased without alarming the farmers I come into contact with. An AR would definitely raise eyebrows.
When actually going calling, I usually carry my Sako. But I have killed a number of incidental coyotes with the Ranch Rifle. I wouldn't want it for my only predator gun, but it does serve a function. By the way, neither Ranch Rifle has ever jammed, ever, even with a variety of aftermarket and factory mags.
