Although I know a few guys who could probably pull a shot like that off, I probably know a lot more who would attempt a "hail mary" and mess it up.

I've HIT targets beyond 600 yards myself, but I'm not sure what I typically shoot really has enough poop left in it to bowl a bull elk over at 600 yards. More than that, it seems that however fabulous I think my mental notes, compass bearings, etc. were of where he was standing when I hit him, by the time I let him settle down a bit and cross whatever terrain's in-between us, the lighting conditions have changed and where I thought I knew he was standing - often isn't. And because I have this annoying tendency to be shooting mid-to-late-afternoon, darkness seems to fall twice as fast when I'm trying to find a wounded animal. And they always seem to go into the deeper, darker woods, making it all the more difficult to find and then haul them out.

I like DRT hits on elk, and the closer I am, it seems the more chance there is of that being the result.

In addition to offering better shooting conditions, there's nothing like a stalk that lands you smack in the middle of a herd of elk. Noisy, smelly, interesting critters. My first experience with that made me a forever believer in the cow call.
