Thank you, Gert, highly informative. Backs up what my outfitter taught me while "touristing" in Kruger, after my hunt in Z A was over.
In one of the "tourist camps" we had a bull, with one broken tusk approach us through the scrub. He came up within about 20 meters, before he turned away. My outfitter estimated his "good tusk at around 40+ kilos....
We discussed him for hours later, the hair on the back of my neck still standing up.... something I will NEVER forget. Thank you, Gunter.
