If you do not have a mover just set up a static target. At ten yards face the way the target would normally come from and set timer for 5 sec. So you are shooting a static mover at reduced time. Then you repeat but start, faceing to the opposite side. Then move back to 15 yds and repeat. Keep going, do the 3 shot strings at 20 and 25 until you have done all 48 shots.You will be suprised how well it works.
