I may have a opportunity to go on a 5-Day with Kuche in Limpopo for Blemsbok, Impala and Warthog in 2019. I noticed they recommend 7mm and up for mininums. I have a 6.5 Creedmoor (pretty much a ballistic twin to full pressure 6.5x55 loads) that I shoot really well with 129 Hornady Interlocks @ 2800 fps. They have been very effective on Whitetail and Feral Hogs to 200 lb (Haven't shot anything larger), They exit on shoulder shots on the hogs. I have not taken any Texas Heart Shots. I don't really have anything between 6.5 CR and .338 Win Mag right now. .338 seems a little excessive (A 200 Grain Winchester Soft Point will pretty much decapitate a deer on a neck shot) and while an excuse to buy a new rifle is nice I've sold my .277-323 rifles for the most part because they didn't do anything I couldn't do better with a 6.5 or .338 WM. Has anyone hunted with less than 7mm with Kuche and did you have any issues? Do you think the 6.5 CR is to light for Warthog?
