Frangibles are widely available, but many shops don't carry it. I've been reloading it for a year or more. (9x19, 38/357, 38 Super, 45 ACP, .223 Rem., 7.62x39, x54R, 303 Brit, 7.62x51, 7.5 Swiss, 30-06, 35 Rem, .358 Win., (even 30-30...not for tubular magazines), etc.

I believe RUAG/RWS has a frangible line, too.
http://www.rws-usa.com/ Now that RWS has a marketing deal with WMT (and facilities in Florida, I believe.... yes, Tampa FL
http://www.ruag-usa.com/ ), you may find it at your local Wal-Mart soon.
You notice that most frangible ammo is not encased in a jacket, but is rather a 100% compressed powder composition.
PM me if you need further info on my experiences with this fodder.
