In another post I mentioned weighing some Hornady 75 grain HPBTs on my digital scale. It is set up in my computer room on a TV type table, which is as level as I can get it.
Two nights ago I weighed 100 and segregated them by weight.
Last night I recalibrated the scale and started to weigh another 100 and noticed the size of the different weight piles wasn't following the previous night. So I decided to re-weigh the first nights bullets.
The 75.2 grains were now 75. The 75.1s were 74.9. This may or may not be a big deal, but I'm going to try this with powder, especially in the 25 grain range I'm using with Varget. I'd be more concerned with changes in group in that situation, and I'm surely going to try it with my 9mm load weights. I don't generally load to the max but this ain't kosher!
I have a 505 for backup. I'll also see if I can detect a change on it from 75.0 to 75.2.
Thanks for any suggestions,
