GemPro 250 vs. beam

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?

My opinion, keep loading with the beam scale for a month or two, and throw every charge on the Gempro before loading it. Understand the correlation between the two scales, if it varies based on weight (same delta at 25 grains as at 80 grains), and if the Gempro measues differently over a fast dump, slow dump, trickle, etc. Once you've got a good feeling how they correlate, use the one you like the best and use the other to corroborate set-ups and to double check every 10 or 20 rounds.

I have a crappy e-scale that tracks my beam +.1 grain pretty consistently. I use it to back check as described above. One time I must have had a beam stick - the e-scale caught a load that was 2 grains high. Made the extra effort worth it!

Let us know how you like that Gempro!

Wow. My GemPro 250 has been and is dead on with my beam scale. I even have a cheap electronic scale that is closer than what yours is.

varminth8r is dead on with his recommendations.
