I have reloaded that Norinco yellow box .223. As far as I am concerned it is as waste of a good bullet,primer and powder.When resizing, I found many of the flash holes were significantly off center.I also found that the commercial Winchester brass I was using with the same load gave better consistency (tighter groups, less deviation in velocity shot to shot).If you are unconcerned about producing top quality reloads,just banging away, then go for it.
