I've used 150 gr and 165 gr ballistic tips in my 30-06 for at least 25 years. They are super accurate, especially out of my Ruger M77. And I have killed probably 30 deer over the years with both the 150's and 165's. That being said, they can be pretty destructive on the meat, especially if you hit bone. They are essentially a hollow-point with a plastic insert. I have recently gone to Hornady interlock bullets, they seem to expand well and hold up better.
