Sorry, but based on your own videos, your math doesnt work for how long it would take to drop powder for 100 rounds. Your video clearly shows that you can do 2 round in 30 seconds. So that is 15 seconds per round. (100 rounds * 15 seconds ) / 60 sec/min = 25 minutes for dropping powder. Then you have any additional time it takes for setup, teardown, and cleanup.
I'm not saying that this trickler is slow, but saying you can do 100 rounds in 10 minutes using a manual dropper and the IG trickler is just lying.
100 rounds in 10 minutes equates to a round every 6 seconds. I havent seen ANY system that is weighing charges that can do the kind of speed you are referring to. To be clear; I am talking about the complete cycle time it takes.
