Re: 223 on 650 Dillon
I make 2 passes on the 650 when loading 223...usually. YOu can do it all at one pass but things dont always go as smooth, so what I do is deprime/size in one pass, then run them back thru seating primers, powder and ball. That way, you arent sizing while doing everything else as sizing causes the most press movement/force. That way, you aint got powder splashing up out of the cases all the time. I also use a lee decapper with a modified rod in stage 1, then stage 2 is my dillon carbide size die without the mandrel.....I dont like running things into the case mouth. If the cases are boogered to where i need to do so, they get tossed into a box to get used at a later date....those are rare though.
Otherwise, just be sure your press is set up correctly, indexed, etc and have at it. Watch for corncob pieces cause they will jam sheet up quickly than you can believe. Ball powder is the way to go, but if you must run stick, be sure you are using a powder check cause that stuff will bridge on ya. I also use rubber bands on my powder bar to give it a swift kick back after dropping the charge. Seems to help things a bit.
After tens of thousands of rounds of 223, I still aint got it perfect yet! (I load all of our jr HP program ammo so my press..and me...get a heck of a work out!)
