I have no experience with Leopard attacks but Boddington has experience and makes some interesting points. If I recall correctly he was not impressed by the penetration of buckshot on cats and felt that within 10-12 yds the shot from a SG didn't disperse wide enough to make it any different from a rifle.

Leopard bites invariably become infected and one can become septic and quite ill.In the past many died.I have been told that when they attack they usually don't hit just one hunter but several.Not Good.
