Keep your non-dominant hand (the weakest one) and your elbow underneath the shotgun as much as possible.
Rest your thumb of your dominant hand along the stock.
Place your trigger finger (the index finger of your dominant hand that you will use to pull the trigger) onto the front of the receiver. You should never touch the trigger unless your target is in full sight.
Fold the last three fingers around the shotgun grip.
Raise your dominant elbow above your shoulder. Place your non-dominant hand under the armpit area and feel for the shoulder pocket. This is where you should position the butt stock in order to feel less of a recoil action after shooting.
Keep your dominant elbow high when in a position to shoot. This will prevent the butt stock from slipping on your shoulder or biceps during firing.
Position your cheek against the stock of the gun, according to the ARM Climate Research Facility website. This will help you to aim correctly and to be consistent in shooting your target.
Bend your forward knee slightly to help absorb the shock of the fire. Keep your back leg in a straight position to use as a shock absorber.
Squeeze the trigger slowly and firmly when shooting the shotgun. Do not pull the trigger with a sudden or jerky action.
Point the muzzle of your shotgun upward and carry it higher than your head.
Know that every gun is considered a loaded gun and never forget this important rule, even for a second.
Aim your shotgun only at a target you wish to destroy. Do not make the mistake of carelessly aiming it elsewhere, even if you are certain it is unloaded.
Maintain the direction of your muzzle at all times, even during a fall or while stumbling. Risking injury by spraining an ankle or other minor injuries is not nearly as tragic as accidentally shooting someone during a fall.
Avoid climbing on anything while carrying a loaded weapon. You could easily fall or drop the gun, causing it to accidentally fire.
