Ahhh, you guys ought to go after 'em thru the brambles on a dark night, that is, after you ticked him off and didn't hit him right
They can take a hit and keep on trucking, but if you hit em good and shut their four wheel drive down they will go down. I've seen well hit boar with shots thru the liver or neck go miles, and like Ed said, they aren't scared of you either. Last year on a drive hunt thru a thicket one went out from under the brush at my feet, I had stepped up on a stump, took a breather, and off it went. See em run back thru between the drivers too.
I use 30-06 180gr A-Frames, a bullet I trust, Waidmannsheil, Dom.
