When it comes to the firing position, you must put your gun snuggly into the shoulders by keeping your hands in a similar position. You must put your butt very firmly on your shoulder. If you are unable to put the shotgun tightly into your shoulders then it would surely push a kick and you may have to suffer from a drastic or almost unbearable pain. Your body will automatically absorb such pain by keeping the shotgun on your shoulders in a very tight manner.
