Use Barnes 168 TSX out of 30-06 on a mule deer few years back, the shot was approximately 180 yards, hit him three times in the shoulder and he was still standing, all three shots hit the same place and exit wound was as big as a fist, had to finish him off with friends 6mm and soft point bullet, dropped like a rock. Ever since then I started using lighted bullets on deer.
I had similar experience with the TSX from my 300 Weatherby. Mine penciled through a shoulder and top of the heart. Two more shots took him down. First bullet looked like he had been shot by an arrow with a field tip.
Switched to the TTSX and it is devastating on deer.
