Multitudes of elk are killed every year with arrows, round balls, and various other projectiles that carry nowhere near 1500fpe. Bleeding holes through important body parts are what kills stuff, not some magic amount of foot pounds.
Multitudes of elk (and deer) have been left to die a slow death from inadequate weapons / bullets and pisspoor shot placement. If the shoe fits, wear it. GFY in advance!
Have you ever read Col. John Patterson's account of the man eaters of the Tsavo? His book relates a bunch of lion hunts he was on. His gun was a 303 British. Over and over he makes the statement "the lion was hit but wasn't taken". IOW, he wounded a bunch of lions because his gun wasn't up to the task. He might have created more man eaters than he stopped. When he killed the 2d man eater, he shot it 3 times with the 303 before switching to a 450 to finally kill it. Use a caliber that's up to the job.
