74. Apr 23, 2011. #2. Re: JBM and Stability. * Stability. Calculates the Miller stability factor. This formula was derived by Don Miller and published in Precision Shooting. This formula is much better than the antiquated Greenhill's formula. Stability value should be in the range of 1.3 to 2.0 to ensure bullet stability.JBM Trajectory doesn't use DA. I would recommend this. It is super easy and gives good data as long as the correct info is entered. I can print a JBM card using just altitude and "STD atmosphere at Altitude" and be good out to around 1k. If I need real time data, I use a kestrel for DA and Shooter App on my phone.Ballistic Coefficient The ballistic coefficient for the bullet being used. It is almost always obtained from the manufacturer, but can also be measured. 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.DOS ballistics program from Tioga Engineering, Pennsylvania.

Park Falls, WI. Nov 5, 2013. #1. Years ago I when I was on the search for a decent free external ballistics program for the PC, I came across WinBal (Windows Ballistics) and was wondering if anyone else is familiar with this program. If not, I think you can still find it online somewhere- just Google WinBal.zip and you should be able to find it.

Define a coordinate system where y is the range variable, x and z are perpendicular to the trajectory where x is to the shooters right and z is up. Then rewrite the derivative d u / dt a = d u / dt = (d u / dy) (dy/dt) = - k (u - w)+ g. But dy/dt is just the velocity in the y direction (down range) written u y, thenJBM has been providing free online ballistics calculators and info for approximately fifteen years. During that time JBM has written custom ballistics software for a number of different platforms including desktop workstations and embedded processors and microcontrollers.

Calculate a trajectory card from bullet, velocity, firearm and atmospheric parameters. Density is calculated using input density altitudes. Muzzle velocity is found by using linear interpolation between two velocities measured as a fuction of temperature. Explanation of termsThis is done by measuring the drag of the standard bullet. This standard bullet has a ballistic coefficient (BC) of 1.0. Other bullets of the same shape but different size have different ballistic coefficients. The drag function and BC are then used to calculate the drag coefficient and therefore the drag on a bullet of similar shape to the ...Ballistic's world renowned JBM ballistics engine delivers the gold standard in calculations that other applications compare themselves to.

I mostly use JBM and use Ballistic on the Touch when I'm away from the computer. Ballistic has the option of using the JBM engine, so its results are the same. If you had a small laptop or netbook that you just wanted to haul along to the range, then Litz' program from Berger will certainly work.

Calculation of the sectional density is straight forward. For a 300 grain, .338 caliber bullet, the sectional density is: SD = [ 300 gr / (7000 gr/lb) ] / [ 0.338 in ] 2 = 0.375 lb/in 2. NOTE: With the common definition of the sectional density, the units have to be converted when used with drag functions, velocity, etc, to convert the in 2 to ...
