Shooting from sticks is a problem. And the distance can easily be 200 meters.
Most of the hunters in my vicinity have shot wild boars from a blind, rifle on rest, all their lives.
Then they go to Africa, and get a surprise. Shoot standing, from a stick. Ups!
And usually they dont shoot on paper. Bulits are expensive, and not for punching holes on paper, you know...
Booking agents like big numbers of hunters and do not advertise about skills required.
Pay and go.
But to be honest, I haven't seen an outfitter's web pages stating the importance of the client having a skill in shooting from a stick. And this is very specific way of hunting for Africa.
Yes, not to wound, and not to pay for wounding is an incentive. And moreover, springbok is one thing, but buffalo, lion, elephant or leopard is another level, and same rules apply, much higher trophy fees plus added risk of charge later.
But it does happen.
When I got more experience and was able to notice details by safari number 3, I was observing a group of hunters in the camp, and listening more carefully to small talk. I was hunting apart from them my list of animals, not being with them during daily outings, but bush TV tells a lot.
They had a roughly 20% wound-loss ratio. Including one sable.
