We have a bunch of open fields, and a 150 yard shot isn't out of the question. I have used Lightfields for years in my 12ga...with a 4x12 or a 3x9 it's only a matter of holding steady.

With my loads, I used to sight in 1½-2" high @ 50 yards...which would still be high @ 100, but coming down to dead on roughly 150. But again, those were Lightfield 3" 12ga shots.
