Lapua Offers Free Advanced Ballistics Software
Lapua has used sophisticated Doppler radar to calculate the actual air drag of its bullets throughout the course of bullet flight. Drag coefficients derived from these continuous field measurements make it possible to calculate bullets’ trajectories with great precision. By using Doppler-radar derived drag coefficients, trajectories can be predicted much more accurately than when using the simplified one-number BCs provided by most other bullet-makers.
To enable shooters to calculate trajectories (with the Doppler bullet data) more effectively, Lapua now offers a FREE special edition of QuickTarget Unlimited (QTU) software tailored for Lapua bullets. QTU is a very sophisticated program that allows you to choose among 12 different drag models. QTU also allows you to compensate for rifle firing angle, rifle cant, wind speed, atmospheric pressure, temperature, and humidity.
Using this free software, you can calculate the trajectories of Lapua bullets to a great degree of certainty. With the QTU Program, as starting values, you need only bullet type and muzzle velocity (add windspeeds if known). The software will calculate bullet drop, velocity and energy as a function of distance and flight time. Complete QTU instructions are in the QTU Manual.
