Lee Loadmaster Primer Tray - Fits Winchester boxes

thingiverse

Used red_rider95's primer tray as a guideline and modeled up a tray that fits CCI and Winchester primer flats - no more trying to fit a square flat into a round tray. Mouth of the tray will need to be trimmed if you have any elephants foot but otherwise it prints pretty easily. Try flips the primers very quickly - no more sitting there shaking for a full minute hoping that last one will flip.
