I recently used .308 Win 150g Nosler Ballistic Tip to take Chital. I wasn't all that impressed. The Chital is a bit bigger than a Fallow but is still a light bodied deer. I found that on a through the chest heart/lung shot, the projectile didn't exit. I recovered the projectile from the the opposite side. On bringing back home I weighed it and found it was only 70% of original mass. While it did the job, I wouldn't want to use it on anything more solidly built or tenacious. In future I'll probably go back to Nosler partition style.
