"Hi Mike, do you use the locking stud on the adjustment slide of your safety scale to lock in your setting?"
I don't own a Lee Safety Scale. The one's I've handled in the past made me know that it's a false economy.
I have an RCBS 505.
If you're going to spring for only ONE high-end piece of equipment, spring for a quality scale by one of the major manufacturers, along with a set of scale weights.
