A couple years ago I posted about a gut shot I made on a deer due to a free handed shot I made. I found the deer, still alive; it got away and I never recovered it.
I'm not ashamed to post about my bad shots. I thinks it a good learning experience.
I don't care who you are, if you hunt long enough and are good enough to get multiple shot opportunities; sooner or later you're gonna miss and it doesn't matter what the weapon of choice is. That's just the reality of hunting.
