Just added the Lee Auto disk powder measure to my turret and boy it is great! I used the chart that came with the measure and weighed about 8 or 10 drops to confirm the charge weight. They were all within 0.1 to 0.2 grains of each other using WIN231 powder. I really like this upgrade and as long as you use some way to test weigh your charges at set up, I belive it is as safe as anything out there.
