[QUOTE="Mikecr, post: 2918347, member: 1521"] Regardless of your scale type, it's important to learn it. This is a dynamic measure (not static), so you need to watch it's operation. Beam scales like any other have dampening -that can be tuned. Electronic scales can be tuned for more than just dampening. But in the end, the scale operator needs to be able to detect a good result -vs- suspect. If you watch carefully with the ChargeMaster, you can detect a suspect dispense, and you can detect when it's right on the money (to the kernel). If you seen a clump drop just before the beep, it's and overcharge. If you see it jogging at it's slowest prior to beeping, like it wants one more kernel to fall but it just doesn't happen, and eventually it beeps anyway,, then you know it's an undercharge. If that last kernel had dropped and it immediately beeped, it's on the money right there. Before long you can get really good at knowing a perfect dispense. To aid myself in getting there, I purchased a far more accurate Acculab scale to watch the dispensing, the scale response, and then read the real results. Once I had learned the scale, I sold off the Acculab, as the CM scale is a far better general reloading scale. This learning did not actually me cost that much. Having done the standard CM mods, I also learned that there was an attribute needed that was not among standard mods. The overall motor speed needs to be tuned to the particular powder, to get that last kernel drop w/beep. You can't do this with the programming. But again, this measure is dynamic, and so it can be tuned one way or another. I put a potentiometer in-line with the motor, with access to it's adjustment, so that I could quickly tune motor speed for optimum with a given powder. With that I was able to better the accuracy of dispensing, to the kernel, which can be higher resolution than the CM scale. I usually end up slowing overall dispense time 2-5seconds, which is less that programming offers. But this is different. A very fine tune. I can leave the program in default settings with this. [ATTACH type="full"]499680[/ATTACH] What RCBS should have done is further deveop the product with a second purpose-built trickler tube, operating in parallel. A smaller tube and externally adjustable for the particular powder. Stop the big tube under charge, at trickle phase. [/QUOTE]
