With that said, I'd use whichever Foster slug tends to shoot more accurately/true to POA in your gun. So if I were you, I'd buy a couple boxes of each and go try them all out to compare. When I was growing up in NJ, I seem to remember dedicated rifled slug barrels with sabots being the most popular way to harvest white tail....I went the muzzle loader route instead.
