Mickey--

I am with little practical experience as I have only one Double but I definitely got"the bug" and must have more.

it seems that there are various catagories of "african" doubles for different classes of game to be taken at different ranges. Please correct me if my percerptions are grossly in error

Light (or all round)African level Doubles like the 9.3 or 375 flanged with the lightest relative weight and about 3000 ft pounds energy.These are good for PG out to 200+ yards, can be scoped and will do larger game(buff etc) in a tight.

MEDIUM African Doubles in the 450/400 class are generally heavier weight rifles and can take PG, big cats and Buff reliablyon up to Ele. They can used effectively scoped out to ?200 yds. Their energies run around 4000+ft pnds.

HEAVYAfrican Doubles seem to be those Doubles with 5000+ ft pnds in a 10 pound + rifle and above with less flexibilty of range for PG but excellent put down for Big DG.I guess you could ahave a SUPER HEAVY class with 577's etc as well.

I am guessing the 500/416 would fall in this last class but have extented range for PG and could be scoped for this purpose.

All the above is pure opinion and conjecture from a novice but--
If you already have a "heavy" Double in 470 or 500 and a second scoped Double is considered which one with the most flexibility(effective kill distance) for both PG and Big DG would you choose?
