JBM Ballistics accuracy The Art of the Rifle: GeneralThe 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 ...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.Table 6 compares Nosler and Litz BCs for the Ballistic Tip to determine the average overestimate which is 6.33%. The Nosler 120 grain NBT in .284 had the highest overestimate at 12.7%, with the 115 grain .257 NBT and the 125 grain .308 NBT also having substantial overestimates at 10.76% and 9.58%, respectively.

The classical equation to calculate gyroscopic stability is as follows. ( Sg S g) is the gyroscopic stability factor, and must be above 1.0 if the bullet is to remain stable. Sg = 8π ρairt2d5CMα A2 B S g = 8 π ρ a i r t 2 d 5 C M α A 2 B. The variables are as follows: The gyroscopic stability factor. A bullet is stable if Sg S g is over 1.0.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.Calculates the power factor and checks divisions for IDPA, IPSC, TSA, USPSA and SASS. Output shows whether or not the division is made (green/red) and by how much in percent. Calculates the free recoil energy and velocity using firearm weight, charge weight, bullet weight and firearm velocity.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.

Its low power means it gets by with a very thin brass shell casing, a contributing factor to its nice price tag. Such a thin casing enables a rimfire primer, which is struck through the brass by the firing pin. Still, the 22 LR's muzzle velocity is nothing to scoff at.JBM is working on some iOS applications including a ballistics calculator. There are currently no plans to support Android systems. IDPA Classifier A simple iOS application for entering and tracking IDPA classifier progress.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.
