Outfitter/PH: Before you pay a dime, definitely ask for references from previous hunters. Any quality safari company will have clients that you can call, and you can ensure the hunt is what you are looking for.
Fences: Poaching is a SERIOUS problem in SA. Without the fences, all the animals would get poached. It sounds like an exaggeration, but many of these places are employing full time armed squads of anti-poaching teams to keep their animals alive.
Additionally, consider the size of the outfit when assessing whether the fences mean “shooting fish in a barrel.” Many of these outfits have huge areas, (80+ sq. miles.) and many of our western “wild” hunting units are boxed in by impassable interstates, effectively fencing the animals into much smaller areas.
As an example: One outfit may have 80+ sq. miles fences in, with only animals indigenous to the area. In years that the conditions are right, they may need to reduce animals numbers by large numbers. (The same way that the DNR sets harvest quotas in the US.) Since the outfitter can’t suddenly increase his clients by a hundred to match the animal population increase, he either culls the animals or rounds them up, tranquilizers them and sells them. They are still very much wild animals. They sell those animals, and a local outfit with 2 sq. miles purchases them and releases them. Hunting on the first outfit’s property is hunting wild animals. Hunting on the second outfits property is hunting wild animals in a barrel.
Bullets: most PH’s are incredibly experienced, but often that experience is not with modern bullet technology. Our PH’s were very open to new things, and after seeing ELDX perform, were very pleased with that bullet. In Rokslide fashion, I used a too-small cartridge and it did great. 6.5 Creedmoor with ELDX.
