I didn't assume anything wrong other than the fact you hit your arm when shooting. The back picture clearly shows the elbow locked. You're clearly leaning back and all out of kilter. Your feet are parallel to the line of target which would prevent you from getting a sound foundation and having everything else in tune. You only shot it down because I said it. You have some serious form problems but don't want to hear it. I mean, these are not minor flaws. They will limit your consistancy and accuracy. You say leaning back is a bad habit. It sure is when it causes other problems, like shooting from a tree. If you're not willing to learn don't ask the dang question. And when you reject everything I've said again I quit. You'll have to start rejecting everyone elses stuff. Almost everyone who's been at this game a while has pointed out things. They all point to problems or limitations with how you're doing something. You can listen to experience and maybe learnor excuse it all away. I don't really care. You're perfect as far as I'm concerned.
