Where to find once fired 44 Special Brass at a reasonable price?

Don't waste your time with 44 spl brass. You will just have to reset your dies when you switch back and forth.
If you really need 44 spl brass, best is to buy it new. Various makes have large differences in wall thickness, this makes loading mixed lots a PITA.
Some companies just cut down 44 mag brass, other have dedicated 44 spl dies for the brass.
