I have seen a 30 cal ballistic tip, ether 150 or 165 factory load, I can't recall which, fail to completely penetrate a small whitetail buck from a 30-03. The deer was maybe 170lb live. I shot a big Saskatchewan buck, 275lb , on the same hunt with my 7mm Rem Mag 160gr Accubond through both shoulders, did a 3ft run, straight down. Personaly, I prefer my bullets to pass through, giving maximun tissue damage the entire length of travel, as well as giving an exit hole to bleed from. I muvh prefer the Accubond or Partition to a ballistic tip for anything larger than antelope. Just my opinion.
