About AmmoLots
What is AmmoLots?
AmmoLots is a free tool for shooters to track ammunition performance, ballistics data, and long-range steel shooting. Record your range sessions with chronograph data, or log steel games to track hit rates and scores across distances.
Whether you're a precision rifle shooter tracking lot-to-lot variance, a long-range steel shooter logging hit percentages at distance, or just want to keep records of your range trips, AmmoLots provides a simple way to log and review your shooting data.
Early Access
AmmoLots is currently in early access. The database is still being populated with ammunition entries, and new features are being added regularly.
If you don't see your favorite ammunition in the database, you can add custom ammo entries for your own use, or submit a feature request to have it added to the main database.
How to Use AmmoLots
1. Create an Account
Sign up for a free account to start recording your range sessions.
2. Record a Range Session
After each range trip, create a new session with your chronograph data. Record average velocity, extreme spread, standard deviation, and group size. Add photos of targets or ammunition boxes for reference.
3. Log Steel Games
Track long-range steel shooting separately from paper groups. Use Hit/Miss mode for simple hit rate tracking at each distance, or Scored mode for competitions with multiple target sizes and point values. Set up scoring templates for repeatable match formats.
4. Track Your Data
View your session history to see how different ammunition performs in your firearms. Compare lot numbers, barrel configurations, and environmental conditions.
5. Browse Community Data
See what other shooters are recording in the public sessions feed. Find ammunition that performs well in similar firearms to yours.

Frequently Asked Questions
Is AmmoLots free?
Yes, AmmoLots is completely free to use. There are no premium tiers or paid features.
Can I keep my data private?
Yes. Both range sessions and steel games have a "Public" checkbox. Uncheck it to keep a session or game visible only to you. Private data will not appear in the public listings or be visible to other users.
Note: private data may still be included in anonymized, aggregate analytics in the future (e.g., overall hit percentages at a given distance with a given ammo). These would never include identifying details about who shot the data.
My ammunition isn't in the database. What do I do?
You can add custom ammunition entries for your own use when creating a session. If you'd like it added to the main database for everyone, submit a feature request or contact support.
What chronographs are supported?
AmmoLots works with any chronograph - just enter your data manually. We have entries for popular chronographs like Garmin Xero, LabRadar, and MagnetoSpeed so you can track which device you used.
