Good question. I know guys shoot them in target matches. I load up Nosler ballistic tips (both 150's and 168's for my -06) and shoot Winchester Supremes (Nosler 168 gr. ballistic tips again) for hunting. All I can say is that they posthole virtually every deer I shoot with them....AKA they fall over dead as a doornail. I have shot close to 20 deer with these things and the combined distance that they have all run is at most 20 yards. They are impressive indeed.
