I was lucky enough to see all Big 5 in the Krueger, not on a hunting trip (duh). I don't think I own a gun, much less an AG, that I would point at any one of them, except the leopard. That was the one I was least inclined to shoot, although if I was a landowner there it would be a different story. You can't really see one of those elephants and want to shoot it, IMO, and I am not considered a "softie" by any stretch.
The Rhino is the "other" one. OMG I definitely wouldn't tackle one of those with my deer guns! I know they are taken but I was too close to some, and that is time to back off and call for an air strike.
But the ruminants... they have more deer-like critters that taste good than any place on earth. Impala, Springboek, Eland, Kudu, Wildebeest (no pushover there) and even the little dyk-dyks... ca-riminey. I didn't hunt but I would love to go to Namibia sometime and have a go at some of these (not the dyk-dyks). I would try many of them with the Dragon Slayer, given the opportunity. I am a meat hunter and there is a lot of meat running around that part of the world. Amazing place, highly recommended.
