RE: 223 THROUGH THE ROOF-PROGRESSIVE LOADER?
Its not a progressive, but I recently got a Lee Classic Turret press. It reloads very fast, and set up with a Lee autod Disc it should work very well with .223.
I haven't loaded .223 on mine yet, just 30-06, and 6.5x55 at a rate of around 150/hr without rushing anything.
