I use either an old Lyman-Ohaus Duomeasure for very light plinking loads or a Lyman DPS III. Whichever one I’m using, powder goes on the case, I look into the case to give it a reality check and then seat the bullet. With the DPS in “auto repeat” mode while I’m seating the bullet it’s measuring another load.
I used to weigh with a Lyman scale or use the measure for the powder and then drop an inverted bullet into the charged case and place the case into the loading block. After charging all the cases, I would seat all the bullets after taking a look into the cases for a reasonable powder level.
