You should have your boys over at R&D, Come up with a Gizmo that would stop the flow of shot from the shot dispenser to the shot container, So you can change out shot bars with out emptying all of your shot, I'am always changing bars from 7/8 to 1 1/8. Your SL 900 is the best reloader I have used, A bit of a leaning curve starting out, but once you get the feel of it smokes the competition,
keep up the good work
