The Effect of Wind on Flat-Fire Trajectories, Robert L. McCoy, BRL Report Number 1900, Ballistic Research Laboratories, Aberdeen Proving Ground, Maryland, August 1976, [ADB012872] Exterior Ballistics, McShane, Kelley and Reno, Univeristy of Denver Press, 1953.3DF (degrees of freedom) model that is used in this calculator is rooted in old C sources of version 2 of the public version of the JBM calculator, ported to C#, optimized, fixed, and extended with elements described in Litz's "Applied Ballistics" book and ideas of the friendly project by Alexandre Trofimov.The JBM Ballistics Range Card (shown below) lists ranges down the two outer columns and different ambient temperatures are shown across the top. Each intersection of range and temperature shows two numbers. The upper number is the elevation adjustment in clicks and the lower is the windage adjustment in clicks needed for a 10mph direct crosswind.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 3.53. 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.

Compare these ballistic calculator outputs, particularly the "Maximum PBR" range in the first column. The first is with a 20″ barrel firing M193 at 3300 FPS, the second is a 16″ barrel at 3100 FPS, and the third is a 12.5″ barrel at 2900 FPS. These represent my three favorite barrel lengths for an AR-15.hey everyone, just wondering who uses the jbm app for their phone? is it any good? i saw there was 2 versions. the original is $10 and the "tactical" version is $20..any input? thanksBallistic is a mobile application for iOS devices, such as iPhones and iPads that can be used to determine shot placement by automatically calculating dope through the world-renowned JBM ballistics engine.

The ballistic coefficient falls under the premise of external ballistics and is regarded as the property of an object to overcome air resistance while traveling. For a projectile weighing m kg and having drag coefficient C, the ballistic coefficient B can be written as:. B = m / (C × A) where A is the area of cross-section of the projectile. The ballistic coefficient is measured in the units ...

The 22 LR is a tiny round at only 1” long. 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.CO.
