I have had the same experience when it comes to the Auto Disk throwing a different weight than what the manual says, with most powders I have used. It does not matter if it is a small charge or a large charge, stick or ball powder, the numbers are usually off. And just like you, the actual weight is always lower than their advertised weight. I tend to use their recommended disk as starting point for getting the right number.

That said, I have never experienced a change in the weight thrown by the disks. I always weigh the first couple throws from the Auto Disk and usually a couple in the middle of loading batches of 100 to verify it is still on, and have yet to find a difference of more than .1 in any single throw (usually on the light side). I have never used the double disk attachment and only use it for pistol reloading in 380 ACP, 9mm, 40 S&W, 45 ACP, 38 Special, and 357 Mag.

I agree that you may want to check and calibrate the scale as it may be a simple solution. Or, double check that the Auto Disk is clean and not binding anywhere.
