For rifle ammo, all of which is loaded in the Redding "D" frame press, I set the 10-10 with the check weights to the nearest 1/2g and then adjust the rotary weight to the desired reading, pre-measure the charge with the RCBS ChargeMaster, dump it on the 10-10, trickle to weight, and dump it in the brass.
I only use the BR3 and Lyman 55 for AA2460, or other ball powders.
I load handgun ammo from .380 through .45LC deer loads in the Dillon 550 and use the Dillon powder measure after setting it up by weighing charges on the 10-10 calibrated by check weights.
The Redding measure was relegated to storage after it turned out it was always the one that was wrong when the two scales disagreed during a 500 cartridge test run.
I came to lose trust the Charge Master over time so just use it as an easily adjustable pre-measure. when I first got it I thought it was the best thing since sliced bread. Over a period of a year reality set in in the form of increased extreme MV spreads and I went back to the balance beam as the final measurement before pouring the powder into the brass, and the extreme MV spreads came back down at the same time..
