There really isn't any readily available case today which can be easily modified to .32 Short Colt dimensions. I'd say it will never again be made due to the very limited market demand, and the collector market is probably the only source. Someone may be turning .32 SC cases out of brass barstock, but that gets very expensive. If the Fiocchi ammo is indeed the same as .32 SC, it would be worthwhile to see if you can lay in a stockpile of it. I have never seen it.
