I used to have a tracking collar on about a 180-200# boar. For the most part he would stay in the 12000 acre hunting club, but several times we have tracked him about 6 miles out of the club but every time we dogged him, he would run back to the club. I believe hogs move for a number of reasons. Number one, food & then receptive sows. I also believe they will move out of a area that gets dogged a lot. All hogs will.
I had a collar on a Barr & he was very content to stay on the same branch. We would go in & bay him with pups, then leave him alone & just mess with him about every 3 weeks or so & he stayed put.
Hogs are very nomadic & travel with the food.
cajun i always enjoy reading your posts. A tracking collar on a hog would be an AWESOME way to train some pups !
