[QUOTE="richhymas, post: 2294084, member: 43504"] I originally wanted to blame something with the chrony calibration, but it is more likely that your scale was somehow not zeroed. On an electronic scale these things happen. Static etc can effect the zero. With a balance scale I have had a few grains of powder fall in between the tray and the cup part way through reloading effectively lightening up the load. Conversely, one of the weights could get bumped moving the weight somehow. This is more likely given the pressure signs on the first trip and not on the second. If you work up to pressure again, and it’s off by say 2 grains, you will know that something was off by 2 grains on the first trip. [/QUOTE]
