We rode mules, got up close and personal with the elk. I like to eat a two or three year old dry cow, used a 243 Winchester with a 100g Partition, and the combo never failed as shots were within 75-100 yards. I placed my shot, or did not fire. I think that an 85g Barnes tsx would have done just as well.
Stuff is not hard to kill, practice and be competent with your equipment, have the tools to judge ballistics with atmospherics. If you have a hunting/shooting partner, take careful notice if he slaps the trigger or raises his head up off the gun at the report. Ask him where the cross hair was as the gun fired, if he has no idea, then he will not be a candidate for long range shooting as he will soon demonstrate.
