Last time I checked hunting bullets were designed to bring a quick lethal death to animals. How they perform this I really don' t care only that they do it in a very consistent fashion. Out of all my own experience and whatever has been posted here and read there, even using hearsay partitions always seem to do the job. I don' t know how you can improve on them. I have never lost an animal using them and on the other side of the spectrum I haven' t lost one using corelockts either. Who said a bullet had to be in one piece when exiting an animal anyway? These idiots(gunwriters) that are fueled by the ammo companies money just come up with stuff to muddy the water. There are any number of quality bullets out there(barnes swift trophy bonded. Hornady. Speer Sierra. CT.etc etc etc) and they have been rehashed here several billion times..just pick what shoots out of your gun the best and is a proven killer and forget the shearing off of the nose nonsense about partitions.
