Drag Function. The drag function for the enter ballistic coefficient. New Drag Function. The drag function to convert the above ballistic coefficient to. Velocity. The velocity at which the ballistic coefficient entered above is defined. If you only have one BC and no velocity information, use the average of the muzzle velocity and terminal ...Kinetic energy is a function of the bullet mass and motion. This motion involves the velocity and rotations. It is represented by the following equation. KE = 1/2 M v 2 + 1/2 I w 2. NOTE: this assumes a single rotational axis and forward motion of the bullet. For multiple rotations and non-symmetric bodies, things get a little more complicated. The ballistic coefficient is represents the ratio of the drag of the standard (e.g. G1 standard bullet) bullet to that of the bullet you are shooting. A ballistic coefficient of 0.100 means that your bullet has 10 times the drag of the standard bullet. Bullet Length The length of the bullet.

53. Dec 22, 2010. #2. Brian Litz measured the ballistic coefficients of many different long range type bullets and he published the results in his book "Applied Ballistics for Long Range Shooting". He goes into great detail about all of the "why's" and "how's" in the book. The BC's that he measured are what you are seeing in JBM and Shooter.Terminal ballistics: the study of the interaction of a projectile with its target, whether that be flesh (for a hunting bullet), steel (for an anti-tank round), or even furnace slag (for an industrial slag disruptor)." ... JBM Ballistics, Thanks to krung. Last revised by .long range trajectory, wind drift, and impact energy. This project compares ballistic coefficients advertised by four well-known bullet companies (Hornady, Nosler, Sierra, and Barnes) with those measured by an independent source (Bryan Litz). G1 and G7 ballistic coefficients were determined using calculations at the JBM Ballistics web site.This means that it is the ratio of the drag function and ballistic coefficient that model the drag of the bullet. For different drag functions, the Cs will be different, but with properly chosen Cs and drag functions, the same trajectory will be calculated because the drag force is the same.A modified (modified by R. L. McCoy) version of M. A. Morris' RARDLIFT code with corrections for small arms bullets and medium caliber cannon projectiles. Provides interim estimates of lift, overturning moment and yaw drag coefficients. Inputs are very similar to McDrag (above) but it does require the center of gravity location.

General Trajectory Calculators Trajectory Calculates the trajectory from bullet BC and firearm info. Inputs include muzzle velocity, sight heights, chronograph distance, ballistic coefficient, drag function, line of sight and cant angles and atmospheric conditions.Descriptions % Percentage 1 ELD M (Extremely Low Drag Match) 8.5 2 ELD-X (Extremely Low Drag - eXpanding) 8.1 3 HPBT MatchKing™ 5.0 4 SST® 3.653. 0. 38. Dec 16, 2010. #1. So i was just checking out a few ballistic tables of the 300, and it showed the 165 gr. nosler had the greatest energy, velocity, and less drop at 500 yards then any of the other bullets on the list. Seems like everyone shoots the 180. ….

My understanding is that the JBM range card function uses density altitude. My understanding is also that the temperature inputs are for transonic calculations. Density altitude is pressure altitude corrected for temperature, and, to a minute extent, humidity. It is a measure of air density. 4000 DA is 4000 DA whether the temperature is 0F or 120F.This is a 7.62x39 ballistics chart (external) generated using our ballistic trajectory calculator. This round is most used in AK-47s and their variants.. The average 7.62x39mm bullet is something like a 123 grain that is fired at an average of at 2,350fps The charting below follows the trajectory all the way to 1000 yards in steps of 50 yard ...General Trajectory Calculators Trajectory Calculates the trajectory from bullet BC and firearm info. Inputs include muzzle velocity, sight heights, chronograph distance, ballistic coefficient, drag function, line of sight and cant angles and atmospheric conditions.

The ballistic coefficient is represents the ratio of the drag of the standard (e.g. G1 standard bullet) bullet to that of the bullet you are shooting. A ballistic coefficient of 0.100 means that your bullet has 10 times the drag of the standard bullet. Bullet Length The length of the bullet. If checked, the windage is changed to make the bullet cross the line of sight at the zero range -- zero windage at the zero range. Wind Angle. The angle of the wind relative to downrange (0 degrees), 90 degrees is to the shooter's right, 180 is a head wind, and 270 degrees is to the shooter's left. Wind Speed 1, 2 or 3.
