I often see a minimum legal caliber for Zimbabwe and Namibia plains game. Just curious for those in the know, what is a 7mm?
Is it a .284" bullet/groove diameter as Americans would refer to a 7mm?
Is it anything larger than actual 7mm (ie .276") so a .277 would meet the requirement?
Does it refer to land diameter or groove bullet diameter?
Thinking of booking Namibia and wondering if I can legally bring my .270.
