what has happened to JBM ballistics, I use to use this site alot for checking different loads and calibers. As I am just getting started in LRH, It was a very helpful tool. And I really can't find anything in the archives. Hope someone can help! JohnBased on this data, I am confident that best COL length is between 2.53 and 2.60 resulting in sub MOA performance. A bullet seated less than 2.53 is near to the curved o-give. I would perhaps settle on just less than 2.60, say 2.58 for future tests on the Sierra 120 grain. Speed is 2892 fps at the muzzle. Below is the calculation of performance ...My current range has 100, 200 and 300 yard target stands so my thought was to develop the ballistics at those distances, then invest in Quickload and calculate the drop or MOA change at 600 yards, before driving an hour to try to qualify at 600 yards at the new range. Click to expand... Normal come ups- from 100 to 200 = 2. Minutes.Northeast. Aug 16, 2015. #9. bigngreen said: Both jbm, shooter and G7 use the same basic solver so if you a large discrepancy between them you have an input issue and if you have to tweek a Berger g7 number in shooter for 1000 yards you have an issue with an input. I have also found this to be the case.In this video we will be going over how to calculate a firing solution for long range shooting using JBM ballistics. The targets engaged in the introduction ...The JBM IDPA classifier application is a simple application for IDPA classifier practice. It allows the user to enter classifier times and points down and calculates the current classification.

The bullets have been added to the JBM Bullet Library using the G7 drag function bullets measured by Bryan are denoted by " (Litz)" in the description. The G7 coefficients should give better calculations than the G1 coefficients ... Further more, some manufacturers (Lapua) are skipping the ballistic coefficient and drag function all together and releasing tables of drag coefficient versus mach number. Drag Force The relationship between different drag functions and their ballistic coefficients can be shown using the following equations. Modified Point Mass Trajectory. Calculate a modified point mass trajectory from bullet, velocity, firearm and atmospheric parameters. Explanation of terms. Caliber (0.100 to 2.000 in) [0.308] [?] in mm.
