I have experienced and hunted with a few guys that have been charged by Elephant, Buffalo, Rino, Lion and leopard and some which have been mauled by Lion and Leopard and hammered by Rino and Cape Buff.
It seemes that with Leopard the attack will be silent,short and fast (often when not quite ready), but not often fatal but expect major agony and bad flesh wounds.
Buffalo will hook you with their horns after coming through bush even after being hit with good shots. If they get on top of you they use the Boss of the horns to mash your chest int the ground.Often fatal or serious damage.
Getting hit by a Rino often means flying ten meters through the air if not gored and stomped.
Lion will warn you with growling and flicking of the tail.
often fatal if your shots don't hit right.
Charges by Eliphant are the most common as they are so bad tempered and are often bumped into while after other big game. often the charge is stoped but if not, expect to be turned into jelly. I met one PH who had one client run over by a Ele but luckily escaped major damage.
Do not rely on your PH to protect you, he will try, but you only need a bush in the way to stop him shooting effectively. You would be surprised how many clients get hurt on safari.
Happy hunting,
