I think this is more accurate. If you can place the bullet in the vitals, it'll have enough left to kill it. I think you've enough bullet and energy left for elk.

A 357 is runnin 350ish ft lbs, and 900fps. You got a long way to go before the bullet won't kill effectively, provided you can put it where it needs to go.
