Which set of .223 Lee dies are best to use? They have the standard 3 die set and the deluxe die set. Which set works the best and easiest? Also is the factory crimp die needed for loading .223? I am going to start loading .223 and have everything except dies. I have been loading 9mm and .45 ACP. The .223 will be loaded on a Lee single stage press at this time. Any info or experience would be helpful before I buy. Thanks Wanna kill these ads? We can help!
