Got a GemPro 250 today. I let it warm up for 4 hrs. and then calibrated it. Then I leveled out the beam scale. I threw a charge and got it to 53.5 grains on the beam scale. I did this for 3 charges. Dead on all of them. Then I weighed each charge on the electronic...53.66 on each one! Now what? I worked up my final load on the beam scale...Which one do I use?
