I am a big fan of the 500 grain bullet too. I put one solid into my buff beside his tail and it was recovered from the throat! Thats some penetration! He was over 40 yards hauling ass straight away. I hunted plains game at Humani and had several close encounters with elephants. I kept two solids in the bottom of the magazine on my .375 ruger. BTW, That was a backup shot on the buff, he already had a 500 grain A-Frame in the boiler room.
