Do you guys get pass throughs on your shots on Elk?

I have two friends,one shoots a 300 win mag 180 gr bullet,the other shot a 338 with a 210 gr bullet.And neither of them passed through the Elk.The bullets were foundagainst the inside hide.They had mushroomed perfectly and held their retention.

I was surprised that they did not pass through.Neither bullet had hit shoulder bone either,just chest cavity and a rib bone.They are one tough animal.

It's not how big the Deer,But the size of the experiance that matters!!
