RCBS 5-0-5 scale here's my situation....
I decided to weigh an 80 grain charge of powder a little bit differently after i charged several cases starting at 77g of H1000 graduating in .5 grain increments planning on heading up to 81g.
I moved the Big weight out to the 80 grain mark on the scale, put the 0-10 grain slide on 0, put the 0.1 to 1 grain slide on 0. Threw a charge and trickled it up till the scale read dead even with the indicator mark. This is how i weighed all the charges, using the least weight movement possible. ie not moving the tenth grain slide all the way to 1 grain to go from 77 to 78, instead i moved the big weight to 70, the 0-10 weight to 7, and left the tenth grain weight on zero.
I then wondered what would happen if i moved the big weight back to read 70g and then moved the 0-10 grain slide up to 10g while leaving the .1-1 g slide on 0. Should equal the same reading right?or wrong?
Because between the two method's my reading looked like these 2 pictures.
I did this a second time and made sure the scale was zero'ed again.
Dumping all my charges and starting over regardless, this is touchy stuff.....
What am i doing wrong? and which way is correct?
