Re: Boar hunting
We hunt wild pigs here in Texas with just about any centerfire rifle. We've also learned there is not better shot on a wild hog than a head shot right behind or below the ear. They drop in there tracks and there is no loss of meat.
This past fall a buddy killed a 250 lb true russian boar. True russians will have a very thick plate under their skin on there sides to protect them when they are fighting. This boars plate was well over an inch+ thick. After the boar was skinned, we hung the hide on a post and shot it with a .243. Not sure of the bullet used, but the bullet did not make it through the plate and the tip of the bullet was justing sticking out the other side.
That was one tough plate, though the boar dropped in his tracks from the head shot.
Distance is not an issue, but the wind will make it interesting!
