💡Long-Range Do-It-Yourself Tip
This term refers to practical advice given to viewers on how to handle tasks independently, particularly in the context of long-range shooting. In the video, Aaron Davidson provides guidance on using the G7 ballistics program to create a field card for long-range shooting, demonstrating the theme of self-sufficiency in ballistic calculations.
💡G7 Ballistics Program
The G7 Ballistics Program is a software mentioned in the script that calculates and predicts the trajectory of a bullet based on various factors. It is central to the video's theme as it is the tool used to generate the drop chart and field card, which are essential for accurate long-range shooting.
💡Ballistic Coefficient (BC)
The Ballistic Coefficient is a measure of a bullet's ability to overcome air resistance in flight. It is a crucial parameter for accurate ballistic calculations. In the script, Aaron emphasizes the importance of having an accurate BC to build an accurate drop chart, using the example of a 617 BC for a 168 Berger VLD bullet.
💡Muzzle Velocity
Muzzle velocity is the speed of a projectile as it leaves the muzzle of a firearm. It is a key factor in determining bullet trajectory and is mentioned in the script as a necessary input for the G7 ballistics program. Aaron discusses the importance of accurate muzzle velocity data and how it can be validated through shooting.
💡Trajectory
Trajectory refers to the path that a projectile follows through the air. In the context of the video, understanding and calculating the trajectory is essential for predicting where a bullet will hit at various distances, which is the main focus of the G7 ballistics program and the creation of the field card.
💡Field Card
A field card is a small, portable reference tool that contains ballistic information needed for shooting at different ranges. In the script, Aaron demonstrates how to create a simple and a complete field card using the G7 ballistics program, which can be taken to the field for quick reference.
💡MOA (Minutes of Angle)
MOA is a unit of angular measurement used in shooting to express the adjustment of a firearm's sights. In the video, Aaron configures the G7 ballistics program to output data in MOA, which is standard for most scopes, and shows how the field card provides MOA corrections for different distances and conditions.
💡Air Density
Air density affects the flight of a bullet by influencing its drag. The script mentions configuring air density in the G7 ballistics program to account for different altitude and temperature scenarios, which is vital for creating accurate ballistic predictions.
💡Incline
In the context of the video, incline refers to the angle of elevation or depression when shooting at a target that is not at the same level as the shooter. Aaron includes different incline scenarios in the field card, which helps shooters adjust for shots at various angles.
💡Wind Compensation
Wind compensation is the adjustment made to the aim of a firearm to account for the effect of wind on the bullet's trajectory. In the script, Aaron explains how the field card provides wind values in MOA, which can be used to adjust for wind during long-range shooting.
💡Trajectory Validation
Trajectory validation is the process of confirming the accuracy of a ballistic calculation by comparing it to actual shooting results. In the video, Aaron suggests using this feature in the G7 ballistics program to ensure that the muzzle velocity data is accurate and reliable.
