Chargemaster Combo vs Lyman Gen 6
I have been using a Chargemaster Combo for about four years. Six months ago it stopped working and to cut a long story short, I had bought a Lyman Gen 6 before I discovered that I was able to get the Chargemaster working again. So I have been using both, sometimes side by side to compare accuracy and speed. The Chargemaster takes longer to dispense, slows down the flow earlier, and can take forever (10 seconds or more) to deliver that last grain... The Lyman dispenses like a thing possessed... You are provided with a smaller diameter plug that you can use to reduce the flow rate. It also puts the brakes on much later, and I have found that as a result it over-dispenses (by a small margin) more frequently than the Chargemaster.
There is a considerable price difference between the two but I would select the Chargemaster any time. The Lyman is fine if you use it alongside a balance beam scale and check frequently.
