Just because max ethical range is asked doesn't mean they immediately plan to shoot that distance on game.This isn’t really an accurate description of what the OP asked. He asked about the cartridge AND limits to effective range while hunting elk.
Most of the comments gave advice on both topics.
Ethics are personal. If you are legal, you have to find YOUR ethical limit. There is specific range limit for ethical hunting. My limit is closer than [mention]Ryan Avery [/mention] ‘s. I shoot a lot. He shoots A LOT more than me.
Boil down the advice, and you come to this:
1. YES, the cartridge is capable.
2. Practice … and find out YOUR limits, and don’t exceed them.
Good advice for the OP’s question, IMO.
