Maral,
good choice. Chapuis manufacture nice guns that are well made and reliable. They are by far the most popular brand of new double rifle at the BGRC with a number of members owning several. They seem to be well regulated and accurate. We have a number of double rifle events which get shot regularly so we fire a significant number of rounds each year and the Chapuis have proved to be excellent guns.
I have purchased a Chapuis myself in 9.3x74R which will be my first. Unfortunately due to Covid it has taken much longer to be made than normal but is supposed to arrive in April or may which will be over one year in the making. Apparently they have had several workers pass away due to Covid which has slowed production somewhat and the on again off again lockdowns hasn't helped. They are however contactable and as they are now owned by Beretta you can ask questions through them as well. I did and this worked fine at least for me.

Hope this helps, Matt.
