Initially I didn't want to reply because I knew I'd get jumped by folks. This isn't mule deer or proghorn...you are talking about a much bigger and much tougher animal. Yes, I know everyone realizes this. I personally think an elk deserves a tougher bullet than what has been proposed...for two reasons. 1) there are much better choices and 2) prepare for the worst...not every shot ends up being a perfect broadside shot.
Referencing the 7mm 120 grain BT: I've heard many times, and seen in print, that this bullet was intentionally made tough from the get go. Think it was something to do with it being intended for long range pistol rounds but can't be sure.
I wish you luck with your choice!
You only live once, but...if you do it right, once is enough.
