When I do test loads I always weigh each charge on a Redding beam scale and then double check it on a digital scale. I'm actually glad that I did this, or I would have never noticed this.
When weighing using the small counterweight (0-5gr) it is spot on. When I use the large counterweight (5-500gr) it is light by .1 grains when I double check. I'll check the zero and no problem.
Now here's the weird part. I'll weigh it on the digital scale and add powder to make it 5 grains. I'll then put it back on the beam scale and zero it out and everything is fine. After that I went back to zero and checked the zero again and it was spot on.
Think I need to find some check weights
