Make sure all of the screws are tight, both on your scope and stock.

For spring piston air rifles I use a tightly rolled up towel.
#1 - place your rifle at it's balance point on the towel.
#2 - the rifle should just barely touch your shoulder, do NOT jam it in.
#3 - control your breathing, and squeeze the trigger.
#4 - follow the procedure from the above site
