However, there are a couple of other issues here.
First, is that this is obviously not a kill shot, and coupled with the narrative, this detail was obviously not even slightly troubling to the shooter or poster. Wounding an animal happens. Discussing that in an open forum is legit in my opinion. But boasting about it as an accomplishment rather than an error (which we all make) is quite different.
Second, many hunters have a rather ignorant idea of what a coyote represents.
How could you say it's not a killing shot...would you not shoot a game bird from the rear ?
I've killed plenty of coyotees over the years...shot the very same way most while turkey hunting...and will continue to shoot...kill or wound...every coyotee that crosses my path.
As far as most hunters being "ignorant" when it comes to coyotees...
It's the ignorant hunter that won't shoot them.
