Using 223 brass makes the process much easier than the 221, not to mention a whole lot cheaper! I use a motorized case trimmer to cut the 223 down to 1.4". Next, deburr the case mouth. Lube and run the case through your resizing die. You'll now have a necked down 300 whisper rather than a necked up 300 whisper. Wipe off your case lube, and trim down to finish length of 1.355".
Your now ready to load.
