Rickshaw, have read your posts on shrinking group size, and would like to suggest you pull up a You Tube video on "Proper hand placement for Shooting". I have been doing this and shrank my groups by taking this guys advice. When placing your hand on the stock and just before pressing the bang button, release your hand and finger and if the scope cross hairs move off target, you start all over again. Continue this till you get the cross hairs not moving off target at all, press trigger and bullet will hit where you aimed. Takes some practice but after few shots you will see your groups tighten up. This guy gives some good points on shooting and helps shrinking those groups.
