I was not being humorous. Many "new" coyote hunters aim where I drew that red target, then wonder why the coyote spun in circles, yipped, then got up and ran away. It's called a poor shot.
Head shots are pretty tough unless conditions are just perfect, which they usually are not. Train for it just in case, sure, but don't plan on using it very often (ever).
I prefer neck shots or right in the arm pit for INSTANT kills.
