I have on a few rare occasions had to shoot a charging water buffalo that had been wounded. I have also seen how some other people have reacted to the situation and I have found it to be a very interesting experience. I don't like to shoot when guiding as it is not my hunt and only fire when I believe someone will get hurt or an animal will get away wounded. It is very rare for one to charge but the few times it has I let the hunter have the opportunity to shoot it first. Until someone is in that situation they do not know how they will react. It is not like any simulation you could dream up. The first time I was in the situation I was surprised at a couple of things. First thing was physically feeling my heart rate increase at the realisation of what was happening was for real. The next thing was how everything seemed to be happening in slow motion. I noticed details of the animal like a chipped horn and the muscle movement in the neck behind the head as it was coming towards me. I had no thought at all of running and the only movement I made was to step around the hunter and ask him to get behind me. He had shot twice with no effect. I resisted the urge to shoot and waited until the animal got close enough that I was sure I would hit it where I wanted to. It seemed to take forever but I think it was about 15yards when I shot it and hit it just where the spine joins the head as it dropped its head. I believe hunters panic and start shooting at too great a distance and concentrate too much on firing quickly. Patience and remaining calm are what I believe wins out. I had read JA Hunter describing waiting out a charge until you could be sure of a shot and if it was good enough for him it is sure good enough for me. This has been my experience only and it may be completely different for others. If you try this and miss. Don't call me.
