its funny you brought this up. in the old days slugs were not legal in my state. my grandfathers hunting buddies use to hide the slug shells in there socks while hunting.they felt they were a better option than buckshot. my gradfather swore you can hear the difference and because of that he was afraid to use them.today they are not only legal but prefered mosly but you need to have an adjustable sight on the shotgun barrel to be legal.
