As Dave says, "Pie Plate" is the deal. Several variables, here's how mine stack up:
Gun/Bbl: Mossberg 500, 18.5 in bbl. Bead Sight.
Sight: Yah, Bead.
Range: 114 yds. Target: Man-sized, not Deer.
COF: Scrambler from various tac positions.
Shell: Slug, 1oz, 2-3/4 in, std or reduced recoil, both work.
Previously sighted in at 100 yd. Pie plate or go home.
Result: Hit in center of mass. Dead= 6 of 8 on first, all by 2.
Way easier if you have ghost ring or red dot, but bead works.
Not about deer, unfortunately.
