A lower powered gun, deep inside the house with the open window would ‘absorb’ much of the sound. Of course for safety, ensure nobody or a pet is about to walk in front.
To go further in my example, I’d use my 17 HMR with the 20 grain power-point bullet. Not the best coyote option, but he won’t be back after a good hit. One shot only.
I don’t know your exact particulars, not worth getting in trouble over a mangy coyote either.
Another option, call the law. Even police in some areas will dispatch sick/mangy, excessively bold coyotes.
There was a sick coyote at my small airport last Summer, mid day, no fear of people. I brought it to attention of management
, never saw the coyote again.
