in 12 ga sometime, open choke and short barrel.
You will get PAINFUL impacts on your shins, from the MANY pellets that BOUNCE OFF. So much for small birdshot for home defense. you can't trust it to pierce heavy winter clothing and his sternum,man,beyond a VERY few feet from the muzzle. At such ranges, a pistol is QUITE A BIT faster to get the hit with,and a lot less likely for him to grap the gun and wrassle with you over possesion of it, espcially as you try to use a light,phone, etc.
