You're pretty much on your own there. Snag it when/where you find it, but be prepared to pay significant money.

I and my mates have a pretty decent supply of original vintage and recently manufactured brass (Jamison/Captech and Bertram, but forget the Bertram as in my experience it's crappy- to use a technical term) but for future use (if nobody takes up the mantle of manufacturing it) we're looking toward swaging the stuff out of .223 brass. It's not a terribly complicated ordeal, and has been discussed here several times in the recent past.

The Shroeder brass I have is made from 223 rem brass.
I believe I have seen the quality cartridge site had 25-20 SS brass listed at $5.00 + each. At that rate I dont understand why choose it for a new rifle build. The rifles listed in the match results were made by CPA Stevens. 
If I were building a new rifle and wanted a 25 caliber in the performance range of the 25-20 SS I would choose something easy to get brass for something like a 25-222 rimed which is made from 357 max brass. Thats just me though.

The web site shows about $2.50 a piece.  But to your original point, it's surprising if it's popular.  I wouldn't build a rifle in that cartridge just due to such low brass availability.

Rocky Mountain Cartridge will machine it from solid, assuming they are still in business.  Quite adequate if you treat it gently. Do check wall thickness.  One out of the 20 I bought a few years ago was almost like foil at the mouth.  The rest survived a couple-or-three firings unscathed.  I have an adequate supply of Jamison/Captech, so these RMC cases got little use.

Maybe I made the wrong impression I dont want a 25-20 SS I was just curious as to why some other folks did enough to have a new rifle built in that chambering.
I have a BR rifle in 25 hornet so was wondering if any possible ballistic gain of the 25-20 SS over the 25 hornet was worth the trouble with the brass. The 25 hornet is pretty straight forward in forming brass and the parent case very affordable and available. Since I am a long time 22 hornet fan I always have lots of bass on hand.  In a recent visit to the CPA site I see that they offer 25 hornet as a chambering option.
I shoot only cast in my 22 hornet and 25 hornet but when I lust for higher velocity and jacketed bullets I have a vintage depression era BR rifle in 250 Savage that satisfies the desire. It may not be quite up to todays BR standards but it still shoots to the standards of the day perhaps even better with our better quality bullets.

If any of us were completely rational, that person would not be on the forum.

I do understand that logic but for the pleasure of nostalgia there is the pain of brass availability.  Some here have suggested watching the auctions for it but that is a source only for existing brass and unless someone starts making it that source will eventually come to an end..
About 40 years ago I had a Steven 44 1/2 chambered for the 22 Lovell and even then brass was hard to find and all that was available was vintage the most recent run being a special order from Griffin & Howe and that brass was already old..  In the interim Jamison brass came and went so we are about where we were 40 years ago on 25-20 SS brass. Such things keep me up at night worrying about it so for the sake of peace of mind I try to stay with cartridges that are easy to get brass for but I do have weak moments such as in a recent purchase of a 74 Sharps in 40-90 BN.
