With all due respect to the cartridge, i do not feel the 9,3x62 is a 400yd cartridge. It will do everything you need and more out to 250yds but gravity really gets ahold of those fat heavy bullets beyond 250yds.
My 9,3 was a CZ 550 and I loved it. Parted with it shortly however to fund another project as getting back to Africa is doubtful since i am a teacher by profession.
Most plains game can be had at 250yds or closer.....much closer for me as I used my bow for 3 out of 4 animals. The 4th was a black wildebeest at abot 250yds.
If i were to do it again, I would feel comfortable with a 9,3x62 and limit shots to 250yds which most PHs prefer anyways. Otherwise, for flat shooting at distance I would opt for 300WSM, 325WSM, 338WM or there abouts.
I would have to agree, your talking about some decent hold over at 400m with the 9.3 bullets. If you want to stay in this case size, I would highly recommend something on the lines of a 8mm-06 or the 338-06.
With the new bullets on the market for the 325 WSM, this brings new life to the 8mm family. Even these are not overly impressive at 400 yards as far as trajectory but better then the 9.3mm bullets by a fair shake.
Not trying to burst your bubble, if you wanted to use a scope with multiple referenace aiming points, the 9.3 would certainly perform fine with the proper range work to set up the ranges that correspond to the reference points in the scope.
Other then that, the system looks great.

Barrel / Calibre: 9.3x62 seems broadly acceptable. 400m would be the absolute shot of exception; I'd just like to know I could do it if that was the only chance offered at some amazing beast.
I would tend to choose 9.3x62 over the less common (over here) alternatives due to ammo availability.
Do you agree with 22" heavy fluted -or should I simply be thinking of heavier than standard?
Stock: Interested in the comment on stock selection. I realise the A5 is an unusual choice. Not too worried about people laughing (I've taken my AW to the hill after reds, so I'm used to that!). This is to be a left-handed rifle, and I don't particularly like the grip angle on conventional rifle stocks, rather limits my choice! I'd prefer an ambidextrous thumbhole, but don't know of one.
Any other suggestions (synthetic)?
Rimfire: The plan is for summer after next. 90% it will be South Africa. Large, Non Dangerous game.
The reason I asked country, area and animals is because I went through the same thing. A friend tried to talk me into a med. to large Cal. The area I hunted was in the Eastern Cape and wide open. You could set up prone and cover some huge bottoms. I shot a 300 Win Sendero and it worked well. I used NBT's and picked my shots on the larger animals, (all went down with one shot)
When I go back to South Africa it will be further north, shorter shooting and I will use a heavier Cal. in a shorter rifle. Reason being if I see a nice Kudu at say 100 yards there may not be time to wait, like on the open plaines. I want to be able to take a hard quartering shot, and know it will work so the NBT's will stay home and the 375 H&H will be there.
I think your choice will work fine for the distance described.
One last thing, the PH doesn't pay for the hunt so who cares what they think about the rifles looks, If you shoot it well, use it. At first my PH seemed concerned about the weight of the sendero. By the end of the trip he was burning up my ammo shoting rock rabbits over a canyon.
