Just got my press a couple months ago and have had fun loading .40 S&W, .308, and 30-06. My trouble started when I tried to load .223 using RCBS small base dies for use in my AR-15. When the case is pushed up into the powder drop, it's like the measure is cutting the grains of IMR4198 and the force is causing the mouth of the case to be rolled in/down enough that causes difficulty in the next step of bullet seating. When the bullet is seated down to the canelure, you can grab the bullet and just spin it around in the case! It won't come out but it's just loose and will spin around! Is there a trick to make the powder drop smoother so the force doesn't roll down the mouth of the small .223 case? Am I doing something else wrong? Is there a "special" powder insert/funnel made for the .223 case so the load of the powder drop is placed on the shoulder and not the case mouth? I know the sizer is working ok because directly after I size/prime the case I can pick it up and try to push a bullet down in it by hand and I can't cause it's nice and tight. HELP PLEASE! I'm about ready to call Hornady and ask them WTH! Your opinions will be gratly appreciated.
