Plastic Tip Length. Length of the plastic "ballistic tip" if it exists. Otherwise zero. Caliber. Diameter of the bullet. Muzzle Velocity. The velocity of the bullet as either (1) measured at some distance from the muzzle or (2) as estimated from reloading data. The on-line ballistics page can correct for the distance to chronograph.Trajectory μCard - Wind Only. Calculate a windage 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 terms.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 does not use email addresses for any purpose other than historical.

All of the JBM trajectory calculators allow the user to select the drop, windage and lead (if applicable) units. Drop units are either a length such as inches or centimeters or an angle such as milliradians (mils), inches/100 yards, cm/100 meters, etc. The length is a user input value.

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.Jut go to JBM ballistic calculator and use the same bullet for different twist or different velocities. You should be able to understand it better. Going from 20" to 22" might not be significant change in velocity, but going from 16 to 24 could be, it could be critical enough whether your bullets tumble or stay true.Maybe 1 in 250,000 shooters have actually tested, created, and built special software to use a custom drag curve. OP, have you accounted for higher temperatures than the bullet's BC is based on. Most bullet BCs are based on an atmospheric standard like ICAO, Std Metro, or Std. Army.

Ballistic's world renowned JBM ballistics engine delivers the gold standard in calculations that other applications compare themselves to. iPad-Specific Features: JBM Ballistics is a powerful ballistics calculation tool, but it does have some limitations: first, it doesn’t calculate Coriolis effect; second, it doesn’t have separate columns for spin drift (which is calculated with wind drift) and uphill/downhill. For now, we will set aside Coriolis, spin drift, and uphill/downhill calculations. A ballistic coefficient is a comparative value for a given bullet, showing its relative resistance to drag versus a model projectile that has an empirically established set of drag characteristics. There can be as many model projectiles as there are different bullets, but which ballistic coefficient type is used depends on the model and how ...Very entertaining read.
