What's New

  • Version 6.8.3 released January, 2022: Added 2 calibers: 6.8 Western, and 6.5mm Weatherby RPM. Added 105 new loads and 71 new bullets. Fixed bugs reported by users, and changed code that triggered alerts from some security software. Also tested for compatibility with Windows® 11 and found no issues.

  • Version 6.8.2 released January, 2021: Added the 6mm ARC caliber. Added 88 new loads and 106 new bullets. Added the option to import data from Oehler System 89 Data Export (Excel® report) files.

  • Version 6.8.1 released January, 2019: Added 2 calibers: 224 Valkyrie, and 300 PRC. Added 104 new loads and 22 new bullets. Some bullet manufacturers have made corrections to published BC and bullet length values, which we have updated in the bullet library. Given the large number of calibers we improved how the caliber selection list works in the Ammo and Bullet libraries.

    We included the GA custom drag function, which is being used by air gun enthusiasts for pellet BC values. We also developed and included the GAx custom drag function to allow full 3 digit precision for air gun pellet BC values. A GAx value of 0.270 equals a GA value of 0.027. This gives users the ability to fine tune BC values based on observations. For example, if less drop than expected is observed a value of 0.275 can be used with GAx as opposed to a GA value of 0.028.

  • Version 6.8.0 released June, 2018: The new Graph Traces display features a single control that sets both the span and position of ranges that are displayed. This gives you the best view of any range you're interested in. Clicking on the graph at a point of interest opens a data grid showing the exact values of all plots at that range for each type of data. Mach bars from 0.5 to 2.0 in 0.1 Mach increments lets you track velocity while plotting any type of data. The prior Graph Traces display is renamed to Graph Traces (classic) and both the new and classic displays can be used at the same time.

    With growing interest in extreme long range shooting, the longest scale has been extended to 6,000 yards/meters. Increments of 5 and 10 yards/meters are available at all scales out to 6,000 yards/meters with other increments depend on the selected scale as shown in the chart below.

    Added aerodynamic jump to downrange calculations whenever Spin Drift is turned on. Aerodynamic jump calculations need the same information as spin drift, so adding this calculation doesn't require you to enter any additional information.

  • Version 6.7.0 released January, 2018: Added the Laser Boresight Target tool. Laser boresighters often come only with a generic boresight target that approximates a typical hunting rifle zeroed at some typical range using some typical ammo and requires the boresight target to be placed at some specific distance downange. Such one-size-fits-all targets likely didn't meet the needs of many shooters and certainly don't utilize the full accuracy of high quality laser boresighters.

    You can use all the features of Ballistics Explorer to precisely calculate the sight adjustment needed to zero your load at a given range using standard or custom drag functions under a wide range of conditions and then print a boresight target.

    Place the printed target at the distance you specified downrange from the gun's muzzle (printed on the target) and then adjust the gun's sights so that the aim point lines up with the printed crosshair while the laser is centered within the printed laser spot. The gun can be bore sighted at a short distance indoors well enough to get on target at longer zero ranges saving you ammo and time at the shooting range.

    Added the Project feature, which not only lets you save trace data, but all open view and tool window locations and sizes as well as most of their settings. Explore various gun, ammo, and sight-in scenarios, and if it's something you may want to revisit, just save it as a project file. Easily organize your projects using descriptive file and subfolder names; anything Windows® supports.

    Added the following calibers: 22 Nosler, 26 Nosler, 28 Nosler, 30 Nosler, 33 Nosler, 280 Ackley Improved, 375 Flanged NE, 500-416 Nitro Express, 7.62x51mm NATO, 6.5-300 Weatherby Mag, 6.5mm PRC, 6.5x57mm Mauser, and 9.3x72mm R. Added 673 loads and 114 bullets. Now there are over 3300 loads and over 2600 bullets in the library.

  • Version 6.6.0 released January, 2017: Introducing the Drag Analyzer; a tool that lets you see bullet drag not just that of the drag function, but also that of the BC itself along with air density, speed of sound, head and tail winds. You get the full picture for the velocity range and conditions you select.

    Look through the numbers fog to see how various drag functions differ, and in the case of stepped BC values, which standard function they most closely match. In the example above you can see how the BC steps for the Sierra MK bullet correct G1 to better follow G7. Someone using this bullet might find the easily calculated G7 equivalent BC better matches their drop observations, and thus, makes better trajectory predictions at extended ranges.

    Custom drag functions such as those offered by Lapua are now supported and can be used with all of Ballistic Explorer's features including the Drag Analyzer. With a few clicks see just how a custom drag function compares to a standard drag function and if it makes any real-world improvement on trajectory predictions.

  • Version 6.5.1 released January, 2016: Added 2 calibers: 17 Win Super Mag, and 7x65mm R Brenneke. Added 42 new loads and 77 new bullets. More bullet manufacturers are now publishing bullet lengths and some have updated their BC values, so we used that new data to update 247 bullets already in the bullet library. Now there are over 2600 loads and over 2475 bullets in the library.

  • Version 6.5.0 released April, 2015: Added Spin Drift and Coriolis effect to the Trace windows. The new Trace window shown below.

    Added Bullet Stability and Twist Rate Calculator along with Bullet Length Estimator dialogs that open directly from the Trace windows to help users determine the proper twist rate for maximum accuracy.


    All records in the Ammo/Bullet library now include either the actual length or the estimated length of the bullet as determined by our unique bullet length estimator, which is accurate to within 1/3 caliber over 92 percent of the time. Added the following calibers: 6.5x47mm Lapua, 450-400 Nitro Express 3, and 5.56 Nato. Added 119 loads and 335 bullets. There are now over 2560 loads and over 2400 bullets in the Ammo/Bullet library. As before, the G1 BC is displayed for each bullet and the G7 BC is also displayed for those bullets where the manufacturer publishes the G7 BC.

  • Version 6.4.7 released October, 2014: Added the following calibers: 275 Rigby, 300 AAC Blackout, 5.7x28, 6.5x47mm Lapua, 8x57 JS, and 8x57 JRS. Per a user suggestion the splash window automatically closes as the program is started.
