Shooting at targets has nothing to do with hunter safety. If you are a lousy shot, big deal. My cousin used to shoot on an archery team back when there were only real bows. The archery team took on the pistol team every year and beat them every year. My cousin tried bow hunting only one year and quit because he could not get an arrow near a deer. Whenever he got close to a deer, he became so excited he simply could not hit it.
I have seen this "buck fever" many times with gun hunters also. I actually knew one guy that hunted 30-40 years and never shot a buck. If a buck walked up to him, he just sat there and looked at it, unable to move. Anyway, not a great shot? Big deal. You have to start somewhere.
