Nice writeup longdayjake.
About a year ago, a Barnes Tech told me that the expansion threshold for the 6.5 100 gr TTSX was 1800 fps and the approx. BC was .360. I shot some reduced loads at approx. 2000 fps into water filled milk jugs stacked in a row. By the destruction done, I'm sure the bullets were expanding, but I was not able to recover one. After penetrating a few jugs, the reduced velocity barnes bullets would veer off course and exit out the side of a jug.
I was able to recover one at full velocity though that looks similar to what you pulled out of your elk:

I also shot a pronghorn at a little over 300 yds with this bullet. It's impact velocity should have been around 2000 fps, and by the damage done to the pronghorn, I'm sure the bullet was expanding nicely at that range. The shot was not ideal...strongly quartering away... The bullet entered the left rear hip, penetrated through the paunch, diaphram, vital organs, and exited out just inboard of the right front shoulder. The internal damage was extensive.
