About
Lapua Ballistics is a professional-grade ballistics calculator app developed by Lapua, the renowned Finnish ammunition manufacturer. It is the first mobile app to implement the 6DOF (Six Degrees of Freedom) calculation model, widely recognized as the most accurate method for computing bullet trajectories — setting it apart from simpler point-mass or G1/G7 BC-based apps. The app is pre-loaded with the latest Doppler radar-verified Lapua cartridge and bullet data, ensuring calculations reflect real-world performance. Users can also define custom bullets using BC G1 or G7 values via the Siacci method, making it useful beyond the Lapua product line. Results can be displayed in four formats — numerical, reticle overlay, table, and graph — to suit different shooting disciplines and preferences. Advanced features include Coriolis effect correction, cant angle compensation, moving target aiming points, powder temperature sensitivity corrections (up to 4 V0 pairs per cartridge), point blank range settings, and side-by-side comparison of up to three Lapua loads. Shooters can manage multiple rifle and reticle profiles, clone configurations, switch between metric and imperial units, and share calculation results directly from the app. It supports eight languages: English, German, Finnish, Norwegian, Polish, French, Spanish, and Afrikaans. Lapua Ballistics is ideal for long-range precision rifle competitors, hunters preparing for field shots, tactical professionals, and reloaders seeking to fine-tune their loads — all at no cost.
Key Features
- 6DOF Calculation Model: Uses the Six Degrees of Freedom model — the most accurate ballistic calculation method available on mobile — for precise real-world trajectory predictions.
- Doppler-Proven Lapua Data: Always up-to-date database of Lapua cartridges and bullets verified with Doppler radar, ensuring the highest data accuracy.
- Multiple Result Views: Displays results in numerical, reticle overlay, table, and graph formats to suit different shooting disciplines and workflows.
- Custom Bullet & Rifle Profiles: Supports custom bullet input using BC G1 or G7 values, and allows creation, cloning, and management of multiple rifle and reticle configurations.
- Advanced Environmental Corrections: Accounts for Coriolis effect, cant angle, moving targets, powder temperature sensitivity, and point blank range for highly realistic field calculations.
Use Cases
- Long-range precision rifle competitors calculating holdover and turret adjustments for varying distances and wind conditions before and during matches.
- Hunters preparing for field shots by modeling bullet trajectory and effective range to ensure ethical, accurate shots at game.
- Tactical and military shooters applying advanced environmental corrections — including Coriolis effect and cant angle — for precision engagements.
- Reloaders and ammunition enthusiasts comparing custom bullet data against factory Lapua loads to optimize their handload performance.
- Shooting coaches and students learning ballistics concepts through visual graph and table outputs that illustrate how distance, wind, and other factors affect bullet flight.
Pros
- Completely Free: Available at no cost on both iOS and Android with no paywalled features or subscriptions required.
- Industry-Leading Accuracy: The 6DOF model delivers trajectory calculations significantly more accurate than standard BC-based apps used by most competitors.
- Multi-Language Support: Available in eight languages — English, German, Finnish, Norwegian, Polish, French, Spanish, and Afrikaans — catering to a global user base.
- Rich Feature Set: Covers everything from basic holdover to advanced corrections like Coriolis, powder temperature sensitivity, and moving target aiming points.
Cons
- Lapua-Centric Database: The built-in cartridge and bullet database is exclusive to Lapua products; custom bullet support requires manual BC input, which is less convenient for non-Lapua users.
- Mobile Only: No desktop or web version is available, limiting use to Android and iOS smartphones.
- No Sensor Integration: Does not natively integrate with Bluetooth weather meters or smart scopes, requiring manual entry of environmental conditions.
Frequently Asked Questions
What is the 6DOF calculation model and why does it matter?
6DOF (Six Degrees of Freedom) is an advanced ballistic simulation method that models a bullet's full motion in three-dimensional space, accounting for spin, gyroscopic stability, and aerodynamic forces. It is significantly more accurate than the traditional point-mass or G1/G7 BC models used by most ballistics apps.
Is Lapua Ballistics free to use?
Yes, Lapua Ballistics is completely free to download and use on both Android and iOS with no in-app purchases or subscription fees.
Can I use the app with non-Lapua ammunition or custom bullets?
Yes. While the app includes an extensive Doppler-verified database of Lapua cartridges and bullets, you can also add custom bullets manually using G1 or G7 ballistic coefficient (BC) values via the Siacci calculation method.
What shooting data can I calculate with the app?
The app calculates trajectory, bullet drop, wind drift, turret adjustments, point blank range, max range, Coriolis effect, cant angle, and moving target aiming points, among other outputs.
Can I compare different Lapua cartridges in the app?
Yes, the app allows you to compare the performance of up to three Lapua cartridge and bullet combinations side by side, making ammunition selection easier.
