It sounds like you've got your question answered. However, I would always start this kind of query with a question about how well I liked to shoot with irons. Many people aren't familiar enough with irons for them to be any more useful than simply pointing a "bald" rifle. In fact, if there was a concern that a scope might need removal for very close quarters, you might consider some practice sans sights altogether. Bear in mind that I can't say if that has any practical meaning in Africa; I'm interpolating that idea.
Sometimes, the air you 'let in'matters less than the air you 'let out'.
