There's a ground screw on the back of the scale. You will need to run a wire and connect it to an earth ground. Easiest access to an earth ground is through a wall receptacle. Often, the screw that holds the receptacle cover on is connected to ground and you can attach the wire to that screw. You can confirm that with a DMM.

Yes, this, and in addition, I ran a large gauge ground wire from the next receptacle to the front of the scale and touch it when using the scale. It brings me to the same potential as the balance. Standing on an anti-fatigue mat insulates rather than grounds, so the wire helps drain static that would otherwise stick to me.

A mistake thinking that being able to weigh to the extra crumble of a kernel will make a difference in your groups!!

Today I shot in the 1's consistently at 100 using powder thrown with a chargemaster in a friggin tent when it was way windy outside. I have only known 3 old time champions and they have all thrown by volume with Harrels or Chargemasters and all have told me that as long as you are within a 10th then you cant blame your shooting on the charge!

BTW, not making fun cause I got caught up on this as well a decade ago. I also sold my concentricity gauge and bunch of other unnecessary time wasting gadgets.

I agree that Your method can work at 100 yards.

Get a anti static wrist like computor people wear

Would you mind showing what the RF choke is?
I have got mine just plugged now to a Tripp-lite isobar thingy. Stupid question is -if my house has the three prong grounded outlets and the scale has that type of plug too, shouldn’t my scale be grounded now?

Strange yours has a grounded wall plug? Most have a wall wart that powers the scale that converts AC to DC and doesn't even use the ground connection. That's why there is a ground screw on back that allows you to reference the exposed metal surfaces of the scale to same potential as your power source (dissipates static charge) . Your Tripp-lite probably has a 3 prong cord and again the exposed metal surfaces of the Tripp-lite would be referenced to ground. I don't use any power conditioner, plugged straight into wall, no ferrite bead, no choke, use my phone in close proximity, did have a florescent light (converted to LED) and did wipe plastic surfaces with IPA and used dryer sheet and my scale is grounded and doesn't drift, unless wind currents or temperature swings.

Well your right, scale does just have a 2 prong on the converter. Now to find out if the Tripp-lite has any of the screws to connect a ground wire to.

A 10th of a grain changes the vel in 308 sized cartridge about 6 fps with the proper powders. Thats my logic in a nutshell!

The RF choke is one of the clamp on ferrite beads. Here's a good selection for different size power cords. One wrap around the choke takes care of a lot of interference.
