A lot of my practice is at a whiffle golf ball that is about 1 1/2 " in diameter.I don't shoot groups either,but one arrow,then retrieve it.If i can keep most of my misses within an inch of the ball,I'm satisfied. I have my bad days too,and by no means am I an expert shot,but, when you aim small,you usually miss small,and this helps your confidence in a hunting situation.God Bless
