No, I don't think so.

I had one back in the early 80s and I had to buy several of the little powder drums in order to get the proper weight of powder for the various pistol loads that I was loading for. While the chart that came with it was close for me; it wasn't exact and it took some experimenting with a scale to get the proper drum for the charge I wanted.

Good move on your part to confirm the drum's throw with a scale before trusting it.
