I am with the crowd that agrees that with 150 yard ranges you dont need that much scope, especially with coyote size targets. I just recently put together a Remington LVSF in 223 Rem with a Leupold fixed 12X AO. This is a sweet combination and use it mostly as a truck gun. There are lots of scopes out there that will work for you in your situation. I wanted something simple and like you the shots are under 200 yards so I picked the straight 12X.
