Practice Practice Practice!! Sounds like you get buck fever and make a bad shot. Same as last year. When I first bought my bow a few years back. I wanted to be out in the woods as bad as everyone else. But I knew I wasn't ready. And it sounds like your not quite ready either. I'm not jumping down your back. I'm just trying to help out. And yes, You'll still make bad shots. But it will narrow that tunnel of that happening.
Also, In your other thread when someone posted to get a couple buddies to help you look and you said there was no one to help you. But then your "buddies" found him? Looks like it was in a pretty easy spot too. I'm not trying to point fingers over the computer. I wasn't there so I don't really know. I'm just going by what you have posted.
Just gotta Practice before going out again! And by all means don't make a shot like that. Because something like this will happen...
