I sighted it in at 30 yards, then 60 yards..where i hunt i cant get more than a 60 yard shot. I am using a 21" deer barrel which came with my 870. I think they say its rifled, but i think not. I was using a remington slugger 2 3/4" slug that many think are inferior, but have used them for years. Maybe I should try a better slug. I was always under the impression that slugs fly end over end and dont have the best accuracy. With a week away, and bow hunting still on, i need to wrap this up quick. I think i will try a different slug..Thanks for everyones comments!
