50 primed cases in the loading tray, throw the powder in all cases checking weight on every 10th case as I go.
Visually inspect with a light.
Bullets on the left, charged cases in the middle, empty loading tray right.
Grab a bullet, a case, seat, tray, continue.
If the powder doesn't throw consistently, I'll throw to the scale pan and trickle to weight, charging all 50 cases,
inspect and seat bullets as above.
I use an RCBS electronic measure for load development, 4 of this, 4 of that, 4 of the next.
Once I've got the weight, I throw and go.
