RE: Thunderheads for pigs
Thuds will work fine on hogs. The key to hogs is to REALLY know where the kill zone is, because it is NOT the same as deer. A deers lungs go nearly all the way to the back of the ribs, while a hogs diaphram is right behind the shoulder. Shoot a hog very much behind the shoulder and you will never find it unless it was quartering away from you. On bigger hogs the quartering away shot is good because it lets you get to the vitals (which are between the shoulders) without having to punch through that tough shoulder. For a good look at what needs to happen, Google TexasBoars, go to the forums, and there is a sticky topic on "Anatomy of a Hog." Graphic, but it is the real deal, and highly reccommeded for anyone who wants to shoot a hog with a bow.
