I first start with clean .223 brass. I have a crap load of LC brass so this is where I start.
I then re-size using the 300 BLK Sizer die. My co-ax press has lots of leverage for the job. I use a generous amount of lube inside the neck. I check each to insure that the shoulder is back far enough using a Wilson Case Gage. I then trim to length using a drill and my RCBS trimmer. Cuts it like a warm knife through butter.
Next stop is to clean the edges with a power chamfer tool:
Compact Triple-Head Case Prep Machine from Hornady « Daily Bulletin
I then clean them again in my Covington 250 Tumbler and they are ready for loading. I have used AA5744, H110, and AA1680 to load them. I have tried bullets of 120, 150, and 168 grains.
Anyone else make and load their own 300 BLK brass?
