its hard to think that a VOLUME measure would be so close to being precise compared to powder scale on geox 2f.that was a SURPRISE too me.its hardto think that you pour in your powder in a MEASURE ,dump it in a scale pan, weight it and it is almost within tenths of gr.close to powder measure reading .that was a surprise to me, for sure.i expected to see like maybe 2 ,3 4 gr. diffference in my POWDER SCALE reading compared to powder measure.that never happened.
