Can WSSM be formed from WSM cases?
Theoretically, yes. However, I have yet to find a source for forming dies for this application. I have contacted RCBS and Redding. Both say "no". I suppode it might be possible to find a machinist that would design and create forming dies as a one-off, but be prepared to spend some real money.Can WSSM be formed from WSM cases?
sThis is my opinion: They were worthless when they were introduced. I worked on many of them that had 'feeding problems', and the cause was usually geometry, as in the feed angles are absurd, the case shape encourages jamming, and the gains weren't worth all the hassle.

No, you might just as well use the WSSM die if you want to try that route. I have the Redding body die and bushing neck die for .243 WSSM and there is no way to make the WSM cases into WSSM in a single pass. It will require two forming dies (at least) stepping down to shorter cases. I have no idea what the internal geometry of those dies would be to keep the brass from trying to fold over on itself instead of stretching out lengthwise. The necks will require reaming at the least and probably both reaming and turning to be useable. I'm guessing the cases would necessarily need be annealed at least once during the forming process.Aren't they a straight-wall for the body? I wonder if you could just cut down a WSM die for a sizer. In any case, sounds like a massive marketing fail from the cartridge designers. It kills me how many folks think they'll make a killing selling brass to the masses of customers as a sole-source (or nearly so), when that very monopoly is the reason they stagnate; if you even dangle the possibility of them doing it themselves 'open source' style, you make even more money selling equipment to do so before making the same original money on ammo/brass sales when most folks realize it isn't worth the trouble over factory brass
