20ga Box Loader

This is a boxing tool for 20 gauge shells based on the 12ga box loader by ductape. His design appears to tilt back and also have a slant. Mine won't have the slant but does tilt back. I have tried it with a vintage Federal Hi-Power box and a newer Federal Field & Target box. Can be a little tight but it worked fine and inserted just about the entire internal volume of the box.
