6.5x55 is illegal for larger plains game in Zim. 7x57 is minimum caliber.
Quoting myself from 3-27-2017 here:
"That being said, I doubt that a 6.5 is unlawful in most, if not all of Africa for impala, wart hog and such."
In other words:
I totally agree with the Zimbabwe Game Department on their caliber restrictions, as they pertain to larger plains game.[/QUOTE]
That being said, I cannot think of very many cartridges as well suited to hunting impala / warthog size animals, (and N. American deer) than the 6.5x55.
