I and a friend of mine had some unfavorable experiences with early BTs in 270 (130gr) and 30-06 (150gr) both driven at maximum velocities. I haven't completely regained my confidence in them when driven real fast. That said, I have come to love the 115 BT out of my 257 Roberts on deer. It will go through both shoulders without a hiccup.
If I were to go elk hunting with a 7mm08, I'd feel more comfortable with a 140 or 150 Partition. I have never had a Partition fail me.
