Calculate your Ballistics like a Pro! BulletCalc3 does it all.....Metric / Imperial / or Metric AND Imperial!! Generate Dynamic Ballistic CHARTS w/ "GRAPH DATA" Button -> also featuring Ranges of 100 yards / 200 yards / 300 yards / & 500 yards! **Gravity on Earth is Very Reliable & Limits the Distance a Heavier-than-Air Object Can be Thrown at a Given Speed -> Throwing FARTHER requires Throwing FASTER & Sometimes HIGHER -> Evaluate your FORWARD PASS w/ BulletCalc3 & Develop an Arm like a Cannon!!!......or Just Evaluate a REAL Cannon!! BulletCalc3 will Automatically Calculate FPS / Bullet Energies / Bullet Drop due to Gravity at 100 / 200 / 300 / 400 / 500 / 1000 yards!!! *note: the Aerodynamic Drag Coefficient Used is Exclusive to BulletCalc3, and may vary from Published Values. ++ Aerodynamic Drag Values can be Calibrated or Fine-Tuned using Trajectory Data Published on Ammunition Boxes....or also via Range Observations w/ Chronograph & Bench Mount -> Resulting in Improved Ballistic Model Performance at ANY Distance ++ Sound Barrier Turbulence & Bullet Shape Related Aerodynamic Fluctuation are Known Phenomenon affecting ALL Ballistic Calculators -> BulletCalc3 utilizes Simplicity as the Best Approach for Minimizing Model-to-Measurement Variation in FAST Smartphone Based Ballistic Calculation Don't know what the specs on that Bullet Cartridge are? Use the "Web Search" button to pull up all of the information you're missing right from the Shooting Range Calculate Instantaneous Velocities and Energies at any Range Distance you want to!
