This user-friendly calculator will compute your drops accurately, and output a handy “Cheat Sheet” you can print and attach to your rifle. ( �� Excellence - Integrity - Service . ( �� Typically, determining angles by measurement of the ellipse gives only a rough approximation; however, the greater the difference between the major and minor axis (i.e., the more elliptical the bullet hole), the greater the degree of accuracy of this method of pinpointing the trajectory. ( �� ( �� where, ρ is the air density, A is the cross-sectional area of the ball, and C is the drag coefficient, which is 0.5 for spheres (this is obviously simplified; a baseball, with its texture and seams, would have a slightly different drag coefficient). Important: Since there are thousands of bullet shapes the Ballistic Coefficient calculations made below are not 100% accurate, if you are shooting out past 400-500+ yards your going to need to get the exact BC from the bullet's manufacturer. The path or trajectory can be determined by using Point I (PI), the broken driver's side window and Point 2 (P2), the point where the bullet entered the victim's head.

( �� Our projectile motion calculator is a tool that helps you analyze the parabolic projectile motion. Subjects: Trigonometry, Criminal Justice - Law, Forensics. Ballistic Coefficient & Bullet Math : When Long-Range Shooting distances increase, details like ballistic coefficient of your bullets become a significant factor. ( �� But a higher ballistic coefficient doesn’t necessarily mean it is a better bullet. Remember, it doesn't matter if the angle is up or down, the answer is still the same. General Ballistic Trajectory The motion of an object under the influence of gravity is determined completely by the acceleration of gravity, its launch speed, and launch angle provided air friction is negligible. ( �� Almost all rounds have a ballistic coefficient of less than 1.0, but large rounds like the 50 BMG can exceed this normal BC.
