The scale on the left is very accurate and fast. Brand Cole builds each one with his own hands. You will have a year plus wait to take possession. If you are shooting one caliber and a lot of volume it is worth the price of admission.
The scale on the right is my auto trickler with an A&D FX 120i. I have changed the setup a little and now running the Ingenuity precision powder trickler paired with the auto throw. It pretty impressive from what I have seen. Was able to throw 150 powder charges in 1 hour with no issues. Like you said every one of them within 2/100 of a grain.
From my experience, neck tension plays a bigger role on your SDs than a couple kernels of powder. How are you annealing your brass?
Old school, stand it in a tray of water and tip it over at the appropriate moment. I’ve been laying in Lapua brass 100 at a time of the 6.5 PRC. I’m going to continue shooting unfired brass until I have 1,000 once fired and then begin to cycle through. Lapua is annealed. I am going to look to upgrade my annealing once the lapua gets enough cycles to need it. Ideas are appreciated.
