The OP asked about RIFLE reloading, specifically for the .223 caliber and said that he's using a Lee single stage press.
It's true that all Lee's pistol sets come with a powder-thru die, but I don't know of anyone who uses them for rifle calibers. If you want a powder-thru die on your Lee progressive press for RIFLE calibers, you're going to have to order their Universal Charge Die
, which is not listed as a reloading die, but as powder handling equipment.
When I'm loading cast bullets in RIFLE calibers, I have to make the extra step of flaring the case mouth. That's a well established procedure in cast-bullet shooting. For jacketed bullets it's an extra step that is simply not necessary.
For a single stage press that seems like a lot of extra work.
