To be fair, what I'm usually hunting I don't eat, but I fail much more than 77% of the time. Probably most men do.

That’s a pretty ridiculous way to measure predator success. Hunting is a high risk high reward endeavor; a predator can fail to kill in most hunts and still be a very successful species.

For the record, it’s estimated that American deer hunters have a success rate between 6-13%, depending on the method and state. So lions are apparently more consistently successful hunters than humans with guns.
