I would use the aerotips myself.

Used the 348 model on a boar at close range and killed him on-the-spot dead. However, there was ZERO bullet expansion.

For elk, I'd definitely say use the 405gr Aero. I've shot those with 100gr of 2fg 777 out of my Knight and had good accuracy results. They will be my back-up load for my Buffalo hunt - whenever that occurs.
