rifled barrel you can shoot almost twice as far acurately with sabots but they are triple the price and in my opinion depending on what kind you use can have better knockdown power farthest i have dropped a deer with rifled barrel and sabot 140 yds could prob shoot a lil farther but i dont recomend shooting much past 150 its not a rifle. rifled slugs are good too thts what my dads been using for 20+ years so its all in your own preference
