Today I’d like to give you guys some information on some chargemaster reducing inserts made by David Moore. If you’ve not heard of these, it’s a much more elegant approach to the straw mod method of tuning your RCBS Chargemaster Combo dispenser. The problem with the Chargemaster Combo out of the box tends to be that it starts to dispense a charge, and does so at a rate that exceeds the scale’s ability to keep up. So as the Chargemaster approaches the desired powder charge, the scale sends a signal saying “SLOW DOWN” or “STOP” but by the time the dispenser slows down or stops, it’s already overthrown the charge. Now you have too much powder in the pan, and you have to dump it and start all over. There are ways to address this! Read on!
