I've had my Chargemaster for close to 20 years. It's real strength is being able to quickly imput a new charge weight and hit dispense. Great when working up a load for either pistol or rifle. I bought a second pan and by adding hot melt glue to the pans, I got them to weigh exactly the same tare weight. When I remove the full pan I immediately add the next empty pan and while I am dumping the powder into the case, the Chargemaster is filling the next pan. I have not done any of the programming tweaks and mine works at a comfortable pace. I have added the short length of plastic straw into the trickle tube but I haven't used it enough yet to see if it really helps to reduce the powder clumping issue in the trickle tube.
