enough science all`s i can say is if you shoot a deer thru the lung area with my handload that shoots 3800fps out of a 100 grain bullet i will turn that deer`s insides to red icky jelly even at 200 yards and that deer won`t be walkin away . and my 30-06 with a 165 grain bullet shootin around 2800 fps won`t do that ever and i will have to blood trail that dang deer again.
