Ok, thanks for the link and info on the brass.This place has some, it's already deprimed/sized and cleaned.
P.S. - if you order from them and some of the brass are Hornady, make sure you measure it. The brass that Hornady uses for their factory loads with the FTX bullet is slightly shorter than the brass with the flat point bullet, fyi just in case you didn't know that.
