RCBS Chargemaster "Velocity Stack"

The idea came from the injector setups used on Sprint cars and really cool/wild hot rods. A smooth bell mouthed transition for powder charges to travel on for the last inch or so before dropping into the pan.  The intent is to thwart the frustrating tendency for charges to be "belched" onto the pan as a result of individual grains become partially stuck and piling up in the auger threads of the tube. When combined with a little tuning of the ChargeMaster parameters, it is very possible to dial in the instrument to run very reliably and predictably. The LRI Velocity Stack is made from 303 Stainless steel.  They are a slip fit into the auger.  RCBS does a pretty good job of controlling the ID of the tube, however their is a little variance.  As a result we make the tube slightly undersize by design.  A small dab of super glue is all that's required. For emptying the hopper it's suggested to just lift the front portion of the unit and back flow the residual powder back into the hopper.
