Give this a try when you get the chance...
Take a paper plate and trace an old CD for a target (trace the center out as well because that will be your aiming point)
and make sure that you set it up to where the wind will catch it.
Load up some buckshot that your gun patterns well ('00' or '000') and set yourself at 10 or 15 yards. (say two rounds through a cylinder choke)
Try to get as close to the center with a breeze blowing as you can.
*Think of it as a friendly target exercise, trust me it's one hell of a challenge*
