I will be making my third safari with Game 4 Africa next June and I am considering bringing along a crossbow. Are crossbows legal in South Africa? I am shooting a Ravin R20, Ravin .001 bolts and 100 grain broad heads...430 FPS. Whitetail are easily taken at 60-80 yards with it, but how would it stack up against a 600 lb. Kudu or even larger Wildebeest?
