Good to see others using the 17 WSM. I've had a Ruger chambered for it since around 2016, which I bought specifically for use on state land coyotes. I've shot a number with it, with no escapees. Seems that no matter what they get shot with, they always jump and try to bite the wound before expiring.
Which bullet weight did you use, and is there an exit wound? I use the 25 grain loads, about a third of them exit the animal. The rest grenade leaving a mess.
