I have no doubt that if you put the bullet where it needs to go it will kill an elk. What I thought was crazy about that load, though, was how slow it was. I use that ammo for fire forming brass for my 7/08 and just for fun I put a chrono on a few rounds. Some of them where under 2600 FPS in my rifle. For the distances you mentioned it won't matter, but that's leaving alot of performance on the table. Maybe I'm just spoiled from handloading.
