What is aerodynamic jump?
Aerodynamic jump. This is Bryan Litz’s description of this factor: “Aerodynamic jump is what causes groups to slant when shot in varying wind conditions. Basically, when the bullet exits the muzzle into a cross wind, the bullet tries to yaw slightly to align itself with the airflow.
What is aerodynamic jump in ballistics?
Aerodynamic Jump causes a vertical shift in point of impact due to wind moving perpendicular to the flight of the bullet. Its impact increases when shooting in increased crosswind conditions.
Is a higher or lower ballistic coefficient better?
A bullet with a high BC will travel farther than one with a low BC since it will keep its speed better, resist the wind better, and “shoot flatter” (see external ballistics). When hunting with a rifle, a higher BC is good for several reasons. A higher BC results in a flatter flight.
What are the 4 principles of aerodynamics?
Weight, lift, thrust, and drag are the four principles of aerodynamics. These physics of flight and aircraft structures forces cause an object to travel upwards and downwards, as well as faster and slower.
What are the three laws of aerodynamics?
There are three basic forces to be considered in aerodynamics: thrust, which moves an airplane forward; drag, which holds it back; and lift, which keeps it airborne. Lift is generally explained by three theories: Bernoulli’s principle, the Coanda effect, and Newton’s third law of motion.
What are the laws of aerodynamics?
What is drop scale factor?
The Drop Scale Factor (DSF) function allows you to calibrate the BC of your round beyond the supersonic range of the bullet and maintain accurate solutions out to transonic and subsonic ranges. DSF calibration does not impact the supersonic flight path of the bullet.
How much drop does a 9mm have?
While the 1.8 in drop of the 9mm bullet at 50 yards may not sound bad, it all goes downhill from there. In fact at the 100 yard mark the bullet will have dropped -12.0311 in (over a foot).
What is BC on a bullet?
In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.
