External ballistics is the part of the science of ballistics that deals with the behaviour of a non-powered projectile in flight. External ballistics is frequently associated with firearms , and deals with the unpowered free-flight phase of the bullet after it exits the gun barrel and before it hits the target, so it lies between transitional ...
A = bow riser/grip, B = median plane of the bow, C = arrow aiming line and trajectory Arrow flexing both towards and away from the bow handle. The archer's paradox is the phenomenon of an arrow traveling in the direction it is pointed at full draw , when it seems that the arrow would have to pass through the starting position it was in before ...

For example, a 27 kg (60 lb) bow with 80% let-off only requires 53 N (12 lb f) to hold at full draw. Up to 99% let-off is possible. [54] The compound bow was invented by Holless Wilbur Allen in the 1960s (a US patent was filed in 1966 and granted in 1969) and it has become the most widely used type of bow for all forms of archery in North America.
The bow's primary purpose was to shoot birds, as conventional weapons lacked the ability to effectively hunt flying prey. [5] The lighter projectiles from a pellet bow flew faster, so the shooter had a better chance of hitting a moving target. One of the most important changes to the bullet-shooting crossbow was the strong, upwardly curved bow. [5]

Deflection shooting is a technique of shooting ahead of a moving target, also known as leading the target, so that the projectile will "intercept" and collide with the target at a predicted point.
