Bergers are utter crap for elk. They are frangible target bullets, not hunting bullets. Now you know
You can write hunting on the box, but it changes nothing. The bullet he chose they didn't even bother to write hunting on the box.
A-Frames, Trophy Bonded (any version - TA, ELD, Tipped, or regular) or Northforks are tops. Barnes X family, Weldcores or Partitions if you can't get those. Choose a bullet with a SD of 0.3 if possible, at least 0.27 if you can't get the heavies. If it's a monmetal you can go lighter.
