I am not a fan of the 410 slug for deer ,not enough energy.
But I have seen 2 deer put down with 1 shot each from 25 and 35 yds.
Both deer were shot by my neibors kid with sand bags and red dot . Dad was in the blind .
I would sujest a broadside shot only. Less that 50 yds !
If at all posible I would sujest a 20 gau as min.
