How to Track Your Ammo Inventory

If you shoot regularly, it doesn't take long for your ammo to spread across calibers, brands, and storage spots. Tracking it means you never run out unexpectedly, you know what a range day really costs, and you can spot a good deal when you see one. Here's how to do it, with a spreadsheet or with an app.

What to track

At a minimum, record for each box:

Useful extras are the date you bought it, the lot number, and an expiration date if one is printed on the box.

Tracking with a spreadsheet

A spreadsheet is free and flexible, and it's a fine place to start. A simple layout is one row per box, with columns for caliber, brand, load, rounds per box, rounds remaining, price, date bought, lot number, and location. Add a column that divides price by rounds per box to get cost per round.

The catch is that a spreadsheet only stays accurate if you update it every time. After a range trip you need to remember how many rounds came out of which box, and typing in new purchases is tedious. Most spreadsheets drift out of date within a few months.

Tracking with an app

An app takes over the parts that people skip. In Ammo Box:

Everything is stored on your device, with no account to create.

Spreadsheet or app?

If you only own a few boxes and shoot rarely, a spreadsheet is enough. If you shoot often, keep several calibers, or want your counts to update on their own, an app saves a lot of effort and makes it much more likely the numbers stay right.
