Greetings TrapperErick,
Khomas Highland Hunting Safaris of Namibia, welcomes you to the greatest forum on earth.
I’ve barely heard of and so do not know much about the 6.5x68 cartridge.
Presumably it is in the general category of the USA .264 Winchester Magnum ?
Anyway, as 6.5 cartridges go, I am quite fond of the 6.5x55 Mauser, 6.5 Swede, 6.5 Scandinavian or whatever catchy name people want to call it.
6.5 MM cartridges are not well suited to the larger animals of Africa.
However, for the lesser antelopes and warthog, I believe it would be a real peach.
Best Regards,
Velo Dog.
