I don't Barr them so I can't say one way or the other but my buddies caught 4 Barrs in the same 40 acre cut over last year that averaged over 300lbs. They didn't cut them either but the fella who did lived less than a mile from there. I think other factors such as pressure, food and water determine their range. Who knows they could return to where they originally came from that could be a couple of miles away and set up there. I have been doing studies on the range of boars and so far they seem to stay in a 1-2 mile radius and traveling 7-10 miles a week in that radius, a d sometimes do it in one night. They also never use the same trail everyday, but use the same corridors. Same goes for the sows we have studied, but we still have a lot more studying to do.
Sure would like some more info on your studies,
