Fine, but reason must prevail. No guaranty that you can spot Bongo or GF Hog...or sitatunga.
Bongo is a very shy animal and is very difficult to observe. In the video one can see quite a few ones in the saline. Giant Forest Hog too. In my opinion, this saline is a sancturary. I know another PH, Bongo man, Jacques Lemaux, whose motto is "protect the saline" it's the best place to spot and judge the animals. Shooting ruins an invaluable observation station.
Morio's area is a blessed one. How many people can pretend having seen a leopard in daylight, out of parks of course. Red buff aren't a frequent occurence as well.

Not so with LDG eland that are far numerous, sometimes as frequent as buffalos. Though a PH can affirm having n herds of buffalos, it's trickier for eland troops that move no end, the old males travelling less.

In short, a decent hunter can bank on shooting an LDE and a black buffalo. Fair chance for leopard and lion. For Bongo, the area should have animals, and even more old males, and eventually known more or less open spots where they stay or circulate. Same for the rarer GF hog.
Bongo could be gotten with hounds, but that's used in the South, in equatorial forest.............where there are no LDE.
Picking a good PH with a top biotope (litte disturbed) is the best recipe. Christophe Morio is one.
