I have a RCBS Chargemaster Link and have had it for about 3 1/2 months now. Here recently, I noticed I was getting a lot more overages when charging than I had before.

Out of the box, this thing was amazing, very rare to have any over charge unless when trickling, too many kernels fell at one time. But over the last couple hundred rounds or so, it started getting worse. The other night, I was charging 25 rounds with Varget and it had 26 over charges trying to charge just 25 rounds. I knew something was array so I called RCBS. First thing they asked was did I clean the chargemaster and if so, with what. They then explained that the plastic housing will generate static electricity over time and it will affect the accuracy of the machine. I was told to take a new, unused dryer sheet, wipe the entire thing down with it and try a powder test through it. And what do you know, it worked. Who would’ve thought? I’m sure this is common knowledge for most on here but I had no clue. If anything, maybe this will help someone who doesn’t know and may keep them from checking to see how far it would bounce off a wall.

Yes I been using dryer sheets for years in the loading room for keeping static down. Glad it worked out for ya. I make sure for loading room use I buy the non sented

Case in point on static effects. Several years back I was loading some IMR Target rounds on my 1500. When I finished I took the unit and turned it to drain the powder out of the hopper and nothing ran out of the port. I used a small brush and poked and brushed the power out. The powder was clumping together. I was suspicious that static might be the issue (never had been in the past). As a test I wiped down the unit with a dryer sheet and reloaded the hopper and drained it with non issues and the powder didn't clump.

Not sure why I didn't have overthrows but I was using a program change and the straw mood. That powder clumping would normally drive the trickling mode crazy.
 
Even with an AutoTrickler, I target 0.01 to 0.02 gn below actual charge and have a tray of powder that I add with tweesers one granule at a time. If it way over charges, I recalibrate for the powder.

I never knew this.

Thank you for posting this information!
 
I have an update on my RCBS Chargemaster Link. I have found some powder dispense tube reducing bushings on eBay to slow the dispensing flow of certain powders (mainly H4350) and this has reduced the number of over charges 90% or better. The smaller kernel cylindrical powders and spherical powers never had been much of an issue, but the larger sized cylindrical powders were the trouble makers. But slowing/evening the flow with the reducing bushing/adapters has all but fixed my problem. Just wanted to let those that may not know of their existence. I think they cost $11 and come in a S/M/L pack of 3.
 
When I was reloading a lot of skeet round in a MEC Reloader I was told to put a Bounce dryer sheet inside the powder hopper.

I would also wipe the machine down with one as well. It seem to work well when reloading Winchester AA 410 hulls.

Can you give us more information about the reducing bushings? Where did you find them? Part number? Maybe a link?

Thanks!

I get sporadic occasional overcharges... Usually as the hargemaster flies up to the preset charge amount and then drops too many kernels.

Interesting problem & ingenious solution. I haven't had too many problems with my early unit but I did go into & adjust the calibration adjustments. This greatly improved the over/under of smaller charges.

I'm wondering if there would be a way to ground the unit with a wire to eliminate static build-up?
