My RCBS Chargemaster is fast, but not accurate enough for my competition loads. So I take the powder from the Chargemaster and weigh each round on a scale with .02gr capability. Half the time I can add one or two kernels of short stick powder such as Varget to hit the desired weight quickly and easily. About forty five percent of the time it takes three to six kernels to hit the correct weight. About five percent of the time my Chargemaster throws are so bad I reject them, return the powder, and let the Chargemaster start another charge. Sometimes it gives me a warning, but usually not.
In spite of all the tweaks, my Chargemaster will only produce plus or minus a tenth of a grain much of the time, but certainly not all the time. It regularly make a charge which is unacceptable for competition, about one in 20. I want more reliability than that.
But it often comes so close that I can make a near perfect charge (I don't cut kernels) very quickly by adjusting the Chargemaster output on my more precise scale, so in that respect the Chargemaster is worth every penny.
