Re: RCBS Chargemaster 1500 Review By Jim Brown

I was wondering if anyone has experienced this. I have been using my Chargemaster for about 5 years. I have used many of the tricks and tips mentioned and like the product. From the beginning, whether I calibrate or not, I experience a decreasing tare weight of the pan over time usually about an hour or more. When the pan is removed the scale reading is 157.9. After about an hour it has gradually declined to 157.3. It is pretty consistent and the unit still functions, returning to zero before it dispenses. I always use it in auto, but it happens with manual as well. The unit still returned to zero prior to automatically dropping the next charge. I have checked the actual weights with an accurate triple beam and my actual weights are right on throughout the decline. I has therefore ignored this idiocyncrisy.
Anyone seen this?

Re: RCBS Chargemaster 1500 Review By Jim Brown

I have just bought my ChargeMaster 1500 and dispenser and thrown about 200 loads. I have also noticed a few times where if I left charge sitting for 15-30 minutes and come back, the thrown weight was about .4 - .5 grns overweight. I check to make sure it is not some powder kernals falling in after the throw is complete and this is not happening. If I lifted the pan, the pan weight was now registering 158.X instead of the original 159.2. I never checked yet to see if after dispensing another charge or two if the pan weight goes back to the correct 159.2. What I have done in the past is turn off the scale and start all over with the calibration and move on. I have also used my RCBS 5-0-5 to verify the weight and the charge appeared very accurate so it has me a little bewildered as well.

Now that I see someone else has experienced this, I will do some additional testing today or tomorrow to see if this is really affecting anything. If so, I will call RCBS.

P.S. I have not in the past waited long before start using the scale. (Maybe 5-10 minutes. Not sure if that is affecting the issue. Otherwise I love this product so far.

I'm not quite following you 338! From what you typed, if the original weight was 159.*** and the weight is 158.*** after a length of time, then it would be underregistering, rather then overregistering, the original weight.

Re: RCBS Chargemaster 1500 Review By Jim Brown

My reloading room is a very clean, quiet, no moving air walk in closet with temperature same as room temperature of around 68 degrees. Light bulbs are correct non affeting light bulbs.

1. Calibrated scales
2. Weighed the pan which was 59.2, cleared the scales
3. Waited 7 minutes or so and started dispensing

4. After 5-6 dispensed throws, I dispensed a 7th throw. Looked at grains at the end of the tube and made note how they looked just in case a few fell after I walked away. Weight was at 55.0 grains exactly. Walked away for 15+ minutes.

5. Came back and weight was at 55.4.
6. I lifted pan and noticed uncleared weight was now at 58.X
7. Took RCBS 5-0-5 scales out and measured powder and found it to be as exact to 55 grains as possible.

This is what is confusing. If my powder throw is still exact, how can pan weight change in midstream?

The post above me mentioned that he noticed his uncleared weight had changed from what it originally scaled at in the beginning. I was pointing out that I have noticed that once or twice now. WhenI see this, I immediately turn power off and start fresh with a new calibration.

I am working on some loads this afternoon and will see if this happens again.

Thanks for the reply

Re: RCBS Chargemaster 1500 Review By Jim Brown

I have been thinking of getting one and this is all great information. My question is , does room conditions such as air currents, people walking , vibrations or anything else have an effect on it. Someone told me that their's (not RCBS) reguired a pretty sterile enviroment to operate consistently.
