Like others here, I've used a variety of 90-120 grain bullets in the 25/06 for whitetails. The most consistently impressive killer I've used is the 120 NPT. I switched 20 or so years ago to the 115 NBT because of availability at the time and found it nearly the same. I've since used the 115 NBT for caribou and found it works just as well for 3-400 pound animals as it does for 150-200 pound deer.
