I've refrained from posting on this for a couple of reasons.
First and foremost for me, a bad shot on an animal stays with me a long time. I know it happens to every hunter at some point. I also know with the number of animals I shoot every year my kill percentage is pretty high but instead of being satisfied with that I beat myself up over the ones that I made poor shots on.
Most times it's pigs. Be it during spot and stalk in thick stuff and I tried to put an arrow through too tight of a hole in the brush, or from a stand and I do something stupid like not notice my limb clearance is lacking.
That one got me on my target buck a month ago. Top limb hit roof of blind and I back strapped him. Oh he healed up fine. I've seen him twice last weekend and on trail cam pics. So being peeved makes no sense right? So the point is I don't like telling people it's okay, it happens, grab your bow and get back out there when that's not how I feel when it's me lying in bed going over and over it in my mind.
That said if you know what's wrong, what caused the errant shot, fix it, work on it until it's right, and go back and hunt again.
Second, I never know what most people's practice, shooting ability, tuning, head sharpness, ect is so without knowing all that it's difficult for me to say, let it go and get back out there.
But you do know. And you know if you had your ducks in a row or not and you know if you took a good shot or not.
So I'll just leave you this.
It should feel like carp to wound and lose one. That means you have a brain, a conscience and the desire to do it right. So once you quit feeling sick, sit up, address any issues and get back in the dang stand. We only get so many seasons before our Lord calls us home. Make the most of it.
