If you load on a
Rock Chucker, then you are probably dispensing powder with a
UniFlow. Some of the others had very interesting suggestions about brass kickers and brass catchers, but I would be "pimping out" my
UniFlow so that it threw exact charges. It's not a lot of work, but the benefits are substantial.
• Use the small bore rotor for pistol charges
• Add the optional powder baffle
• Mount the UniFlow on its own stand (per the photo) which allows optimal positioning
• JMorris swears by putting the op handle on "backwards" (per the photo)
• Never use the first 10 dumps; put them back into the hopper
• Adjust the setting by averaging 10 dumps. E.g. if you want 3.7gr, then weigh 10 dumps and adjust for 37.0gr.
• Addition of a fat o-ring under the adjuster lock nut will hold your setting longer
• Practice dropping powder before you start loading
Hope this helps.
