Believe it's still the best powder measure. Could be wrong! I know there are other items out there that are good. Maybe someone that has one. Will chime in, and elaborate on it.
No worries got to have a thick skin at times. Believe me that much powder would want an electronic scale. What is your starting load, bullets, brass, and primers.
Just got on the backorder list for end of January. Great customer service, and a lot cheaper than the Amp. See how it goes, but looks like will do the job.
