Track Brass Firings

Start with two buckets for brass. Label them #1 and #2.

Put new brass into #1 and start loading it. Label each container of loaded ammo #1.

When fired, put the brass into the container marked #2. Continue loading and shooting #1 and putting its fired brass in #2 as long as any brass is available in #1.

When gone, start loading #2 and marking the loaded ammo containers #2. When you shoot #2, put its brass into a container marked #3, and so on.

This way you’ll always know just how “used” each and every piece of your brass is.
