I will tell you why I choose an electronic powder measure and you can evaluate the thoughts.
I like the thoughts of a sinngle stage loader, mine is a Hornady.
I like the thought of electronic over mechanical because of constant charges, that did not say more accurate.
I have no concern about warm-up time and i have no concern about speed of measure as I am doing something while the measure works.
Mine is a Pact, which most are but branded under manuf. names, such as Lee, etc.
Blessings
