6XC brass?

[95huskers]

I am looking for some brass for a 6XC. Everywhere I have found it says it is on back order. I have read that people prefer to fireform 22-250 brass rather than use the factory brass but I have never fireformed before and don't know what I'm doing. Any ideas where I could get some brass (even if it is fireformed 22-250)? Any help is appreciated.
