Gryphon,
Basically, the hunter has a shot at the Tom over an impala bait, wounds it in the side, and they then track it for a couple of days in the Kalahari sand.
The PH then uses a Ridgeback , and they track the Tom into young mopane woodland and brush. The dog gets really jittery, and the PH then sees it about 20 yards out. He puts both barrels of his O/U into the charging animal, and his asst. gets a shot off too. The leopard takes the PH in the face/upper body, and pulls him to the ground. It has his left arm in it's mouth and gives it a bit of a chew. The Asst runs up and puts the final shot into it whilst the PH , on his stomach holds it out at arms length.
The PH was clearly saved from a real scratch up, by his leather jacket.
If you get into www.outdoorvisions.com , and go into the preview section, you can download footage of a leopard coming out of a cave and taking the PH out. It's from a video called 'leopard charge'.
