both are excellent!!!
As much as I like the NBT out of a .308 for deer I think it will come apart too quickly at 7mm mag speeds, particularly at very close range. It will definetly do the job on deer and it is an excellent bullet, but then again...so is the partition as it has a very long and successful track record on deer.
Try each and see which one is more accurate out of your rifle and use it. You really can't go wrong with either. The deer won't notice the difference!!!!
You are the bows from which your children as living arrows are sent forth.
