Bullet selection for elk and mule deer hunting

[Penny_wise]

I am looking for bullet recommendations that'll handle both elk and mule deer effectively. I've been shooting Nosler Ballistic Tips for whitetails with good results, but my guide mentioned I might want something with deeper penetration for elk. Shot distances could range from one hundred to four hundred yards, so any recommendations?

It would help greatly if you would tell us what rifle cartridge/caliber you would be using.

I trust Barnes Triple Shocks.
