great powder measure available. Since the measure actually moves very little and is lubricated by the graphite on the powder, used ones are generally the way to go since they show little wear and are plentiful. Great measures have been widely available since about 1970.

Hornady has a nice unit they supply with their presses. There are numerous other brands but those are the most common.
