Good question. Obviously not all Jungle hunts involve the same animals although trapsing through The Jungle one must be ready for cats (any size and make) to snakes, to crocs, to buffalo, to the other biggies (obviously local inhabitants depends on what Jungle you are in).

My ideal need for a Jungle Gun would be for big cats, but I would want to be able to stop a charge of something with tougher skin and a harder to reach brain.

I like the 450NE option, too.
