Jbm ballistic.

The G7 Ballistic coefficient does a better job of predicting the trajectory of modern long ogive, boat tail bullets to longer ranges than the G1 standard, however, it is still not modeling the exact Cd value or shape and will result in errors. Utilizing the popular and well-designed JBM ballistics code, Table 1.

Jbm ballistic. Things To Know About Jbm ballistic.

The drag function to use to calculate the ballistic coefficients. Most commercial bullets use the G1, but for some long range bullets, the G7 or G8 is typically a better choice. Some military bullets fit the G5 and G6 functions better than the G1.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.The distance from the point of the first velocity measurement to the point of the second measurement. This is the distance between the two chronographs. Drag function. A drag function (or G function) provides the forces on a standard bullet for which the drag function was derived. A bullet's ballistic coefficient then relates the drag on any ... The angle of the tilt of the firearm to the right or left from vertical. Positive angles are to the right. Distance to Chronograph. The distance from the muzzle of the firearm to the chronograph used for muzzle velocity measurements. If the muzzle velocity is estimated, enter 0.0 for this value -- no correction.

The twist rate (inches per turn) of the barrel. This value is used to calculate stability. It should not be confused with the required twist calculated by Bullet Drag. The diameter of the base of the bullet. For boattails, this is smaller than the caliber. The length of the boattail from the rear of the bearing surface to the base of the bullet.

Changing Variables of Integration. From the discussion on CD and KD, we know that the acceleration of the bullet is. a = - k v + g. where. k = = p/p 0 G (m)/C. Rewrite the acceleration as a derivative. a = d u / dt = - k ( u - w) + g.
