HERE'S MY OPION IF YOU ARE SHOOTING A SMOOTH BORE SHOTGUN THERE IS NO NEED TO ANYTHING BUT FOSTER TYPE SLUGS. NEWER SHOTGUNS WITH RIFLED BARRELS ARE DESINGED TO SHOOT SABOTS WITH GREATER ACCURACY THAN ANY SB. MY ITHICA 37 DSL 20 SHOOTS LIGTHFIELDS EXCELLENT, BUT I AM GOING TO TRY THE HORNADY SST AT THE RANGE THIS YEAR.
