I recently acquired a UPM MIC ADJUSTMENT SCREW for the small cylinder used with the Uniflow powder measurer…
I have been adjusting it and recording the setting for a dozen of the reloads that I use most often. This makes it quite simple to set the measurer to throw a given charge without much adjustments when powders are changed—all well and good…
If the small cylinder and the large cylinder can be set to throw 25 grains of a given powder, both would have the same volume, but the small one would have less diameter and greater depth to the cylinder than would the large one. Which cylinder might give the most consistency?
I am sure (?) that super light charges would work better in the small cylinder, but what about medium charges—the 20 grain example?...
I suspect that powder types—ball, flake, stick—would make a difference too…
(I have too much time on my hands!!!)
Thanks…BCB
