Of course that is the sensible and simple idea.

Perhaps get made up a versatile single aluminium case for a couple of barrels, two scopes etc, maybe even two butt stocks and it is the air travel case for everything that can be broken as required.

Ability to take a single DR, perhaps with a shotgun, a Tikka U/O with two barrels, two DRs, two shotguns etc.

And then get made up or acquire a suitable case for DRs or Shotguns that deserve them.
