Man, if you actually read my post, you will understand that using those two things has NOTHING to do with differences between the two scales. Is it really necessary to fire from the hip and go negative?
I did read your posts. What I said was not off topic nor from the hip. You chose to write a dissertation on how you believe powder should be weighed and implied when you said "Most of you veteran reloader already knows this" that your way is the right way which is a bunch of crap.
You go on and on about your Gempro but as far as I can tell you have never even seen the AND and you're bashing it based on absolutely nothing but price. The fact that others have trashed their Gempro in favor of an AND seems to really bother you and you're out to prove that your "superior technique" overcomes any problems that may exist. My FX-120i has been sitting here turned on for nearly six months. I calibrated it the day it arrived. It has been at 0.00 grains for the entire time when empty. I have checked the calibration several times with a 100 gram weight and it says 1543.24 grains every time. It's sensitive to a single kernel of Varget which weighs right about 0.023 grains (yes, there are some 0.02 grain steps you just can't get to). It has a five year warranty from a very reputable company (this isn't the only AND scale I have).
If you've got something else to bring to the table other than your way is cheaper let us hear it.
