PyBallisticsA Python port of GNU Ballistics LibraryCreated by Derek YatesUpdated by Brad RisseThe pyBallistics Library is a port of the popular GNU Ballistics Library to solve exterior ballistics problems through numerical integration. It is a lightweight, optimized library for general purpose ballistics solutions. In general, it is targeted at small arms exterior ballistics at ranges under 50,000 yards.This library supports the standard Drag Functions: G1, G2, G3, G5, G6, G7, and G8It is possible to have dozens of solutions in memory at once for comparing loads or different scenarios, and using this library, it should be fairly easy to create an excellent end-user ballistic software GUI. The high speed solution and excellent accuracy are better than many commercial offerings.Exterior Ballistics Primer for Small ArmsExterior ballistic problems do not generally have algebraic solutions. The models are step-wise models, developed using complex doppler radar ranges. Exterior ballistic models attempt to describe how a projectile behaves at a particular velocity by relating it to a "standard" projectile, which was tested in depth.The most common drag function in use is the G1 drag function. Virtually all published "ballistic coefficient" data in reloading manuals and product literature are G1 drag coefficients.

Leica Geovid binoculars set the standard in the segment of laser rangefinding, and they are reliable and indispensible companions for many hunters. With the first Leica Geovid binoculars Leica started a new era of responsible expert hunting 30 years ago. Thanks to our decades of experience and comprehensive expertise – and over 300,000 laser rangefinders sold – we can proudly assert our unrivalled market leadership in the premium hunting segment.

Using the Leica HD-B Ballistic calculator “ABC” (Advanced Ballistic Compensation)Updated 04NOV2022 – This is an older post that showed the mechanics of how to true your Leica Geovid ballistics for use in real life. While the Leica product line has changed (along with their software) the methods outlined here still work. The screenshots of the Leica software application might have changed (Analytics is still around), but the method to make them consistent with another ballistic solver is still valid.–Old post:This post explores how to setup and configure the new Leica Geovid HD-B ballistics software to generate click values in MILS for US shooters engaging targets to 1000 yards (or 925 M). This is primarily aimed at Precision rifle competitors, Tactical shooters and long range hunters who use a variety of equipment to calculate their shooting solution, and already have DOPE (not the Colorado kind) aka drop charts for their load.The goal is to get the HD-B to match up with your known good drop charts so that you can use the Custom load ballistic data in the Leica HD-B out to its maximum distance (1000 yards).Some preliminary information about my example setup:Bullet = 139 grain Lapua Scenar Cartridge = .260 Remington @ 2881 fps Rifle = DTA SRS A1 zeroed @ 100 yards w/ sight height = 2.45″ Barrel = Short Action Customs Bartlein 26″ w/ 8 twist Chronograph = MagnetoSpeed V3 Environmental = Temp = 87.5 F Pressure = 30.17 inHg Humidity = 17.5 % PC Ballistics program = Applied Ballistics Analytics Leica HD-B Ballistics Application page Covert Utility from Josh Madison (useful in unit conversions) Scope is a MIL value turret / reticle with .1 MIL value clicks (tenth MIL values)Step 1 – Convert your units to MetricConvert all your units to Metric – since we want output
