I totally agree about the .280. I've taken lots of game with that cartridge. I only replaced it because I could get a 7mm-08 in a lighter, short action rifle. It's a favorite, just behind the .358 Win. I do feel a .243 is not a good elk gun. Granted, you can't overkill an Elk but there would be too many times I would pass up a shot with a .243 that I wouldn't with my 7mm-08 or .358 Win.
