dd, are you allowed to use a light on your rifle where you're located? My bait site is 145 yds from my house, but I keep a light from my shop shining on it. The shop is about 60 yds from the bait site so I have enough light to shoot with just that. I'm shooting a CZ in 17 Rem on the bait site with a 4x16x50mm Mueller sport dot. I rarely turn on the dot to shoot. I also have a Coyote Light mounted on the Mueller. It is actually my calling light but when not using it on my 243 for calling I just attach it to my CZ. It will allow me to identify targets at over 250 yds. I only put it on the CZ just in case a coyote moves off the bait site lighting and I want to take a shot. I don't normally turn it on or need it, but have it just in case.
Actually I've killed most of the baited coyotes at about 85 yds. where my first bait site was located. I shot 16 at that location, and obviously the shooting is a lot easier, but I'm shooting from my house, and opening the window is not always completely silent. So I moved the site a little farther from the house to cut down on the risk of a coyote hearing the window open. Don't know if any of this explanation will help you, but you might pick up on something to try differently.
