I've utilized a CB to the head and eventually went to the lungs to which did not solve my aggravation with blood all over everything.

Switched to catch pole around the neck, guess you need a better catch pole than my homemade one as I can dispatch a fox and a bobcat easily with it but never a coyote. So, went to standing on the chest, evidently 165# isn't quite enough to accomplish it in a timely manner.

Now, after gaining control with the catch pole I use my trapping hammer to quickly take care of the issue, with this method I find that a mess while skinning is far less common.
