RCBS ChargeMaster 1500

They may also have issues dealing with low, low loads like 0.2 gr. I realize the spec may be +/- 0.1 gr., but that spec is probably only applicable at "normal levels". I know that some of the electronic scales are not as accurate as the very low weights, lower than what is considered normal operating levels.

If you did what was suggested above by NeuseRvrRat in post #17, this might be a good test to verify that.

JMorris,

I just ran your test on my CM using 0.2gr and it did the same thing. I also checked it with 2.0 gr and it did not drift or zero it self.

I checked the Gempro 250 too while I was at it. The GP did not drift, even after letting it set with .2 gr on the scales for about 16 hours. In fact this GP has not even drifted zero in 2+ months, which was the last time we had a power cycle. Both of these units I leave on 24/7 and my shop is climate controlled at 70F. So their ready to go after I check them with my calibrations weights.

I have one of these on my wish list. Right now I'm diving into shot shells head on.

How well does the chargemaster work for load work ups? Is it easy to change the charge weight round to round?

Easy as typing in the charge weight. Load work ups are it's bread and budda..

You just missed the best deal I have seen on them.

From Nov 25-Dec 2 cabelas had them for $200 after the rebate.

Once again any questions I might have had have been answered....
Very happy with the ChargeMaster all loads are consistent. Glade no one had anything negative to say about it. ...

I'm glad you like the Chargemaster1500. I've been using mine for over 5 years for all sorts of cartridge reloading, and it has never failed me. While I prefer to drop some powders using a Harrell measure, the bulky powders need to be weighed, and I have come to trust the RCBS unit for accuracy and consistency. I do recommend keeping it clean and calibrating regularly.

Any powder dispenser that throws charges to a 3/10ths grain spread is good enough through 300 yards.

With some powders, that's good enough through 600 yards.

How much change in muzzle velocity does 1/10th grain of your powders produce? Can you precisely resolve that difference with a chronograph?

I would think it would matter lots more in a pistol load when you are only loading 3-6 - 4.1 gr. total as compared to when you are loading for a rifle when you are loading 25-30 gr.
