Like some, I have used the NBT in the past in my 6MM and .257 Roberts for deer. While I found them to be accurate, I had to follow to many blood trails which I dislike doing. I went back to using Sierra Prohunters, which are about as accurate in my guns, and haven't had to track anymore deer. I do have some accubonds loaded up for these rifles, but have yet to try them out on a deer.
