I think the Swiss and swede are more accurate than french. Also... no need to keep an empty chamber french and swede do for sure. They have hammer that retracts when trigger is released. I'm pretty sure the Swiss does as well.
I read somewhere in the past that the reason the French Mle 1892 revolvers never seem to shoot as well as should be expected is that the Mle. 1892 shares the same rifling pattern and dimensions of the 8mm Fusil Lebel rifle to share production equipment, revealing the French to be more concerned about tooling costs and setup than accuracy as to them it was only meant to be a point blank range weapon. So yes the longer and heavier bullets should shoot better!
You might need to use the right diameter bullets to start with if you want better accuracy in a M92. I get good accuracy from 110 gr and have done well with bullets as light as 90 gr - BUT - all the bullets I used were sized to .327". My experiments with the heavier bullets didn't show any improvements over the lighter ones. The fiocchi stuff is undersized in all my revolvers. Also, apparently there is some variance in the bore sizes of the revolvers themselves.
COTW had (amongst it's many errors) the 8mm Lebel Revolver bullet listed as .323" for years and I think this probably caused some of the confusion.
The reason that some heavier .323" cast bullets might work better is because: .323" is undersize for (most?) of these revolvers; the heavier bullet generates higher peak pressure and this obturates the bullet base so that it actually grips the rifling.
Every M92 i've ever checked had a groove diameter of .327-.328" . I have heard about M92 revolvers that have .323" bores but I haven't seen one for myself.

Well, my 1882 Swiss arrived yesterday. My first antique, and all I can say is "Wow!" Love the fit and finish, the balance is great, interesting design features, it's a work of art! I wish they made firearms with that much care today. Can't wait to shoot it!
