Actually the last rodeo they had was a cow elk shot with the 338 lapua."they kill a pile of animals every year with [ NOT MANY ] rodeos".
That's it! Rodeo free insurance with big calibers
Poor shot placement with a 338 isn’t going to be much different than a poor shot with a 6mm or the like.
Like I said I will still shoot my magnums because I enjoy the rifle not because I don’t think smaller calibers will work. I’ve actually shot more elk with a 6.5 than anything else
