Key features include:
• Rifle and ammunition profiles
• G1 and G7 ballistic coefficient support
• Trajectory table with selectable columns
• Trajectory graph
• Range card with elevation and windage solutions
• MOA/MIL scope adjustments and click values
• Metric and imperial unit options
• Improve BC tool from trajectory or chronograph data
• OBT load tuning tools for barrel-time node calculations
• CSV import and export for rifle and ammunition data
BulletLab Trajectory is designed as a practical field and load-development tool for users who want clear ballistic results without unnecessary complexity.
