Well, what I may need to do is get just the scale for the time being and add the powder dispenser later. Do you know what the difference is between the Rangemaster and Chargemaster scales is (other than the price)? I would be more inclined to get the Rangemaster because it costs less, but do you know if the dispenser can be added to it later. it looks like the dispenser might only work with the Chargemaster. Either way, I am going to have to order a micrometer for my current powder measure that came with my Rockchucker kit (it's less than 2 years old). It cannot throw a consistent charge to save its life. I am always having to check to see what its throwing. One more question: do you know if I need a small screw or large screw mic for my measure based on the age of my kit? Thanks for your help and advice. Merry Christmas.
