I had a yound hunter this past season hunt elk with his younger brother's 300 Win Mag and a 168 AMAX loads that were intended for hunting coues deer. He shot a fairly big bodied bull in the lower shoulder where the bullet, had it penetrated, would have taken out the heart. As it was, the bullet exploded on contact, making a very nasty would, breaking the leg but no damage deeper than about 1/2". It was a brutal tracking job taking part of two days.
I would never intentionally hunt elk with that bullet- way to explosive. I have seen similar Berger shots placed when the outcome was much better.
Another buddy said they tried them for shooting the small whitetails but they blew the capes up too bad to salvage. Did kill with spectacular results on 90# deer though.
