Hoser-

I've shot both 9.3x74r double rifles AND light .30 caliber double rifles.

The recoil from a properly stocked 30-06 is nothing.
The rifles are light and wand-like.

A 9.3 double rifle will need to be somewhat heavier, but they tend to be built light - and the cartridge has much much more energy than the little .30 caliber
The difference in recoil is considerable.

My sense is that there are plenty of the lighter rifles built - and at the price point you're looking to spend, there's no good reason to sell them once they're up and running, and they're a total joy to shoot and cheap to feed.
On this tier of production built rifles, there's no distinction of 'rare' or 'scarce' -- when someone wants one it comes and they keep coming...




Cheers
