I shoot 120 gr Ttsx's out of a 7mm rem mag & 100 gr TTSX's out of a 6.5x47 L at deer. The only one that didn't give complete penetration was the 6.5x47 on a doe that was facing me, the bullet stopped about halfway through lengthwise & made a big mess inside. I can't imagine a 110 gr 30 cal TTSX even flinching on a whitetail of any size.
