Mec has 28 ga loaders and are a reasonably priced loader that gives acceptable performance. Ponsness and Warren also makes 28 ga loaders. The model 375 is a single stage loader that has all the dies on a plate. Two gauges can be placed on a single plate or disc and changing from one gauge to another is very simple and requires NO adjustments. Extra discs or plates can be purchased and other gauges can be installed on them. I have replaced all my Mec loaders except my 10 ga 2 7/8 in loader with P&W.
