OLDPAPPS: Using a .355" bullet I'm surprised you got a MAS Model 1935A to chamber at all.
I have formed cartridge cases for the Model 1935A and its succcessor, the Model 1935S in three diffferent ways:
Using .32 S&W Long, turn off rim, cut extractor grove and trim to length.
Swaging .30 carbine cases to .337" after reducing rim to .337" and
trimming to length.
Lathe turning .30 carbine cases to .337 after trimming to length.
All of the above produce usable cases that will function in the Models 1935A and 1935S.
