Unless it's exceptionally difficult/expensive for you to get proper ammo and/or cartridge brass to handload, I think the simple risk/reward is a bad idea considering you're discussing a classic old rifle that you have an affinity for.
What I think will happen:
If you chamber a round slowly by hand, it will work just fine. However in normal operation, the naturally violent feed cycle and forward momentum of a cartridge self-loading will have a round skip past the extractor and/or subject the extractor to excessive wear.
Someone above mentioned that possibly these rounds could work in a Ruger Blackhawk? The answer to that is NO WAY. I found quite early in my .30 Carbine Blackhawk adventure that even a little too much brass trimming makes them unshootable. They simply chamber too deeply for the frame mount firing pin to reach them and NO BANG.
This whole operation sounds like a real fiasco to me however, I understand that you are in Belgium, so you might have an array of fiascos to deal with.
