If it were me I would bring a .375H&H, especially if you have the potential of being around DG...If this is not an issue, any gun you use for deer, elk, caribou will do fine there for PG..use a good bullet (Swifts, Barnes) and as always, shot placement is everything..I prefer a 30 caliber myself..but lighter will work..30's work better and 33's work even better...an 30'06, 300 Win or above would do great...Typically shots are 200 yds or less unless you are in Namibia where they can be longer..but many times the shots are much less--150-100 or less for most of it..again, depending on where you are at..

If you have never been there before I suggest checking out the shot placement book just as a quick reference by Kevin Robertson..or skip the book and just shoot everything on the point of the shoulder.. game there dies just like anywhere else..especially if you let the air out or take out the main engine ..having said that, game there also has an incredible will to live..depending on where you hunt, they have predators galore from the time they hit the ground until they are on someone's dinner table..that seems to translate to the "toughness" factor that you read about..

As to ammo, BRING YOUR OWN..do not wait to buy there..and when you leave, leave the left over there..it is normally very much appreciated..as it is normally harder to get there and more expensive..as to ammo, I load my own and only use Swifts..not saying they are the only bullet to use, but they do an incredible job no matter what caliber you use..in addition, when I do go there normally I shoot a heavy for caliber bullet..I really like 200gr A-Frames out of my 300RUM..they worked awesome on Impala, Bushbuck, Hyena,Zebra, Eland, Hippo and Croc the last time I was in Zim....all one shot kills with that combo..

I am not an expert but am making my 5th trip there in about 6 weeks..sure I will have more info to put forth upon my return..Also one of my best friends has been there 12 times in the past 6 years, I get a lot of info from him as well..any further questions send a PM or follow up on here..happy to help..
