I just got done putting together a bulgarian ak74 kit and it turned out pretty well. Being a reloader, I hate throwing away any brass, or in this case steel casings. I've reloaded berdan steel cases before in 7.62x39 so I know I can do it if I have too. My questions are twofold: anyone used .224 bullets, and anyone have any published data and if not what powder and charge weight did you use? I know reloading dies can be had from Lee and rcbs on special order for more money. I wonder if there is enough interest here for a group buy on dies...
