I traded for a Herters #5 Ballistic scale today. It was really dirty but cleaned up well. Filled the oil reservoir with 10/40 (don't know what is the correct viscisity to use is) and started to zero. IT IS SENSITIVE!! Had a fan on, on the floor, and it kept the scale from balancing on the bench. Got it levelled up and zeroed. Weighed a 9mm case on my Lyman D5 then weighed on Herters. They read the same except the Herters goes down to 1/20th of a grain. It will register one kernel of IMR 4350.
If anyone has any experience, information, or owners manual for this scale, I would greatly appreciate it!!
Thanks,
Rich
