Shooting a Tikka T3 SL
All shot impacts were at 100 yds into stacked hard cover books.

Sierra 120 Pro Hunter...mv 3,300 mv...penetrated 6" completely shattered bullet fragmented into nothing.

Nosler 120 Ballistic Tip...3,350 mv ..penetrated 7" completely
shattered bulled fragmented, nothing but tiny shards.

Barnes 120 TTSX...3,500 mv, two shots, both penetrated 8.5"
119 grains for both bullets .55 for the first bullet.
.34 for the second bullet.

The second bullet on its way in shed its claws in the form of a circular ring at 6.5" and continued on to 8.5".
Never seen this happen before.

Bullet pathways were both bowed by a couple of inches, not straight.

Pretty impressed with the TTSX. I don't think it would be my first or second choice for elk but have no doubts it would do the job.

I can't say that for the Nosler BT.

Sierra advertises its 120 Pro hunter for medium velocities at deer size game and calls it a varmint bullet for the 7 mag. It is.
