BTW the S "Supra" barrels were intended primarily for short range shotgunning rather than slug.
In France, it is (was) very common to hunt for rabbits (cotton tail like) which was very often a short range job, especially when ferrets are used.
The rifled barrel would quickly disperse the shot so that the prey would stay edible, even in the 10-20 yard range.
This looks easy, but I must assure you that one must be very fast, as the rabbits are usually in the brush such as blackberry bushes, and run like, well, rabbits...
Hunting rabbit over ferret is a lot of fun...
Another S barrel target would be woodcock hunting, also a short range, fats target job.
Boar hunting was not a big thing back in the 20's as they were few and far between, and would have been hunted with buckshot in most cases.
