Mine are still running at over 1800 fps. The last elk I took was at 110 yards using the 168gr TTSX, that bull didn't even take one step, he just fell to the ground. I will admit that the shot was a perfect heart shot so I can't tell you what would have happened if I'd of done a double lung shot but I'm sure that the bull would have died.
I used to be one of those guys that believed that the bullet needed to stay in the animal in order to kill effectively, I no longer subscribe to that school of thought. The TTSX bullets will, quite often, go through an elk very easily and that's not a bad thing, if you hit the heart or lungs. We kill animals by bleeding them out and two holes will bleed faster than one hole, especially if you hit the heart in between.
I've never wanted a bullet to stay in an animal. I've always wanted the most expansion and exit. Seems like the 130 grainer would be the best of both worlds. With a 60% retained weight of a 180 grain Accubond or Partition, the 130 grain Barnes would still weigh more in the end.
That's why I asked.
Thanks
