MONA, Utah – December 19, 2025 – Barnes Bullets and Sierra Bullets are excited to announce the launch of its new Ballistic Calculator, TrueData™. With Doppler-verified ballistics, precise environmental inputs and tools that match real-world performance, TrueData™ equips hunters and shooters with the ability to make confident shot decisions and achieve data-driven accuracy. Visit the websites at www.barnesbullets.com and www.sierrabullets.com to learn more about the app.
“2025 was a big year for product development at both Sierra and Barnes. We listened, we worked hard and in 2026 we are bringing products to the market that consumers have been shouting for. TrueData is no different! This app has been a long time coming – we built, we tested, we refined and we think this app is the most complete and user-friendly ballistic calculator available. We ask that everyone download it, put it through the paces and submit feedback to help us make this thing even better,” said Andrew Sparks, Vice President of Marketing & Business Development.
TrueData™ is available for free on both Apple and Android stores and can be found by searching for “TrueData Ballistics” in the relevant app store.
Key features include:
- Doppler-Verified Ballistic Library: Instant access to accurate, Doppler-verified data for Sierra & Barnes Bullets. Select from multiple drag models, including Doppler-measured curves for supported bullets. These curves capture true bullet behavior across the flight path far beyond the approximations of G1 or G7. With 80+ Doppler profiles and ongoing expansion, the solver adapts to exact projectiles. G1/G7 values autofill for all bullets where Doppler data is not yet available.
- Ammunition Library: Detailed ballistic profiles for Barnes factory-loaded ammunition.
- Build and Manage Multiple Rifle Profiles: Stores multiple rifle profiles allowing the shooter to switch setups without re-entering data.
- Intuitive Heads-up Display: A unified, real-time interface that brings together trajectory data, environmental updates and shot solutions in an intuitive HUD. Every adjustment is instantly reflected on screen, helping users stay oriented and efficient.
- Ballistic Coefficient (“B.C.”) and Velocity Truing: B.C. and velocity truing tools to align ballistic predictions with real-world impacts.
- Bluetooth Connectivity: Automatically imports precise atmospheric data from external meters like WeatherFlow and Skywatch BL for shooters who demand exact inputs without manual entry.
- Virtual Rangefinder: Quickly estimate distance when scouting terrain or setting targets without a physical rangefinder.
- Target Card: Build and store preset targets with their distances and holds, helping the shooter move efficiently between known landmarks or steel targets.
- Live Environmental Inputs: Pulls real-time atmospheric data from current locations to keep ballistic solution aligned with actual conditions.
- Stage Timer: Simple countdown timer for practicing transitions, positional shooting or timing drills.
