The idea was .357 Mag performance and six rounds in a snubnose revolver, all with less recoil.
I don't know about brass and ammo availability.

Might be that it's still fairly new and production hasn't caught up with demand, same as the .17 Fireball when it came out.
Brian Pearce had a .327 Federal reloading project published in the February, 2009,
Handloader (#258). 12 bullets, cast and jacketed, 16 powders, and 3 factory loads. He used a Ruger SP101. According to the article, Freedom Arms is offering the Model 97 .32 H&R Magnum with an extra .327 Federal cylinder, Taurus is offering a "concealment revolver," and Charter Arms is also offering revolvers.
I found this link to the Taurus revolver:
http://www.taurususa.com/products/product-...tegory=RevolverThe cartridge is listed as ".32 MAG" and I assume it is the .327 Federal since there is a separate category for the .32 H&R Mag which they no longer carry.
I checked the Freedom Arms site,
http://www.freedomarms.com/, but I didn't see the extra cylinder.
Charter arms lists three revolvers called the "327 Patriots."
