I haven't been to Africa hunting, but it is #1 on my list, hence the reason I read this forum. I've read for years that African game is tougher than game on any other continent. Is there any scientific basis for people stating this mantra so often? If so I would like to read it.
It is also stated that elk are very tough animals, and feral hogs are quite often given status as having toughness of mythological stature.
My experience with feral hogs is extensive, due to the fact I live in Texas and hunt a lot. I own land and numerous family members own land, I've killed a bunch of hogs. If you have proper shot placement a hog goes down. My daughter uses a .243 on hogs and is deadly. Many people think a .243 is not enough on large feral hogs, I disagree. My one elk was killed with a .270. I won a raffle in 1983 for an elk hunt and in 1983 I was two years removed from college and a .270 was all I owned. My .270 worked great. I've seen whitetail run for miles when shot by a 300 WM poorly placed and I've seen whitetail DRT when shot with a .223 on many occasions. I'm not a proponent of hunting deer and hog with a .223 though.
One of these days I will get an AR in .260 Remington but until that time I'll hunt feral hogs with a Marlin 336 30-30 that I've invested quite a bit of time with. I've definitely had some runners when shooting hogs with a 30-30. If recovered I noticed my shot placement wasn't very good. If my shot placement is good then I don't have to track.
When I get to Africa for plains game I'll either take my old .270 or my 6.5x55 in a modern action. Why? Those are the two rifles I use the most. They are superbly accurate and I'm very comfortable with them. I have two 30-06's that are accurate enough but I've found the less recoil the more accurate I am, no exceptions. And muzzle brakes are not for me.
I also do 90% of my practice standing with a bipod. I find it very easy to hit targets when I'm sitting and have a good rest. Standing I am 2MOA at 100 yards on good days, 3-3.5 on bad days. I hope to shrink my groups to 1.5 eventually, which gives me four years. For that is when I plan on going to Africa. If a PH doesn't want me because of the cartridge I use then I guess I won't go.
