There seems to be a rather "us centric " response to the question which whilst interesting is slightly less than useless in regards to the laws in the OP's country. In my opinion I’d not bother with either of those two, unless you really want one of them, then I would pick the 7x64, get rid of the 270, and see if you can get permits for other barrels. Then save for a large game rifle for your African hunt
