Both guns will be more than accurate enough to get the job done. Go with the gun that you can shoulder the easiest. Pick up the two and compare them, then the decision will probably be obvious.

I'd avoid the combo deal. The scopes they come with aren't worthy of the rifles they are on. When you put a $50 scope on a $500 gun, you'll get a gun that shoots like you paid $50 for it.

My .223 has a Nikon Buckmaster 3-9x40. I wouldn't hesitate to buy another, and I certainly wouldn't go with anything cheaper.

If you are hunting at night, a 3-9x40 is as big as you'll want. Anything larger, and you'll be too slow locating some of your targets.

I'm not a big fan of heavy barrels for coyote guns. Coyote hunting, especially in the daytime, involves a lot of walking. And the action, especially in close quarters, is very fast. I have never missed a coyote because the accuracy of my gun has let me down.
