RE: Max effective range with rifled slugs vs. ...
I took a whitetail doe at 192 yards
(laser rangefinder) with winchester supremes.Performed flawlessly.Very accurate and sighted in 3" high @ 100 i am 6" low @ 200 with a marlin 512 slugmaster.Thats the farthest i have taken em.4 others at ranges less than that.Hope that helps
