Not foxes but i was out shooting rabbits about four months ago and seen three rabbits in the corner of the field approx 250yds so i drove slightly closer about 100yds or so, put the cross hairs on the rabbit and i could see the second about 10ft behind it hopping around, I waited a second or two and both were in the view so pulled the trigger and both fell, picked them up and the round had pasted through both necks. chuffed !!! two birds with one stone!!!
