I use the 100 gr. TTSX in my 257 Wby Mag and my 25-06. Both rifles have taken a pile of big game and I have only recovered 2 bullets which still weighed 97 and 96 grains and I have never lost an animal to either rifle. In fact most shot have been bang flops. The 25-06 is 3350 FPS and the 257 is 3716 FPS.

If you find yourself in a hole....quit digging
