The OP only offered three choices. I assumed that he was talking factory calibers... not custom stuff. From personal experience, I started killing coyotes with a 223 w/ fiocchi 40 gr ammo... and dumped several in the dirt... but when I started shooting my 204 w/fiocchi 40 vmax.... I never shot the 223 again.
I shot some with the 22-250 and 243, but when I wanted to get SERIOUS.... I now own a 20-250AI w/55 gr bergers...and a 22-243AI w/80 amaxes. These two are the ultimate coyote calibers. But if I could only have one choice of the OP's three... then the 243 would cover a lot of coyote killing situations.
yeah, what he said. hard to swing a fence post!!Whatever caliber I suggest something lightweight. I started calling with a heavy Rem 700 VS in 6mm Rem. It was way too much gun for a calling rifle. Most pelts were destroyed beyond sewing. I used the 223 a lot then fell in love with the .17 Rem in a sporter weight classic model. It is so much more fun watching that lazer beam of death exact its toll.
I am looking to get a Calling rifle. It will be a bolt gun. I have not settled on what round to get. it's down to 223, 22-250, or 243.
