If you have missing ammo they may ask a question, but likely just that if anything. I don’t recall ever having an ammo count departing RSA, the guy in the little room just looks at my permit and the SN on my rifles to make sure they match. I lock and leave.
In Botswana they counted and intently so, on the way in and way out. I also think I was charged a tax or fee per round entering and maybe some kind of tax for the rounds I fired there. April was my first trip to Botswana and the customs/firearms was interesting, not bad, just interesting. Way more modernized, equipped and formal than Zimbabwe. I had ladies coming and going. On entering they seemed set aback by how to categorize/count my ammo since I was coming over from Zim I had a combination of loaded ammo and empties. She got it sorted after talking to a couple other gals.
Upon leaving was the funny part. The lady asked what I hunted. I said an elephant bull. She asked if successful, I said yes. The looked concerned and recounted my ammo again. She then pointed out I was leaving with only one round less than I entered. I said yes, he fell easy.
It was the first time I’d ever had them actually compare my ammo count entering and exiting. And made for a funny exchange since I did only fire the one round in Botswana. I was using my double with open iron sights and had checked everything with some shooting in Zim.
Zimbabwe is the strangest to me on rifle/ammo permits. All happens in a tiny room with a table and a single chair. No computer, just someone with a uniform and a phone. Then there are like 3-5 more people crowding into the room also with phones. The uniform lady will write on your permit (you pre-print the page and bring with you from the US) and then she and the rest of the entourage will snap pics on their phones of your permit, your case, rifle, ammo, etc. Just snapping phone pics like some gaggle of teen girls.
And then the ammo, they can’t see through clear MTM cases, they must pull them apart and fiddle fk around with all of it. And have no conception of ammo coming in boxes of 20-rounds. They literally hand count your full box of ammo to 20, whether in factory cardboard box or clear plastic MTM…taking the rounds out most the time…almost like using individual rounds like counting your fingers and toes….while pausing now and then for everyone to take a photo on their phone. Mark my words, when you visit Zim, you’ll be like holy hell…Will wasn’t kidding, these cats just took like 47 pictures of my gun, permit, and individual bullets.
In RSA and most places, they don’t care on your ammo count leaving as long as it’s not over. I’ve left ammo with PH and friends a number of times.
Don't get caught up in brand names with imported commodities. That said, I stand with SKB of Orange, CA! (don't buy the economy versions...my Son's was cracked to hell by African airports, but their HD versions survived 6 trips and many others at home..and I have a 4-rifle case of theirs with wheels!!!) SKB also has a policy (and decals on all cases...) IF any lock, handle, hinge (all easily fixed via screws) gets damaged in-transit by...you know-underpaid/overworked idiots...they will overnight ship anything you need!!! (Will a "Pelican" do that?) I've never encountered pelicans in Africa, as most of us don't hunt coastal areas. LOL Sales& Marketing BS.
