I haven't used that particular bullet, but would be very suspicious of it. I have used a few ballistic tips in other weights and cals and have found them to open very fast. This might be alright in bullets heavy for the caliber, but in bullets lighter than normal I would think it would have poor penetration even for deer.
I used to load 130 Hornadays and Speers in the 308, and I thought they worked pretty good for deer and antelope size critters.
