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?
Haven't tried them, but I've read good things about the Woodleigh 160 PP, very high BC; and Lapua Mega 155, BC about like Oryx. I can drive tacks with ELD-X 143.I'm going to give the Norma 156 Oryx, 140 A-Frame and Partition and 130 TTSX a try. I'll find something it likes that gives adequate pentration and expansion.
If I don't find something I like I'll try the 6.5-284.
Funny- but a 6.5 Creedmoor is perfectly capable of taking a moose.
