SLUGS !!!
IMO buck shot is good for 25-35 yds MAX Farther away deer are lost to much
I would recomend Brenneke K.O. slugs .
Not only do they shoot great out of most smooth bore guns but they are cheap $ 1.79 a box at Gander Mountian this fall
I would buy a red dot .
I have found I can pick up moving deer better with it and it is better in low light
