How long should the trigger pull on a target rifle used in the prone position be compared to trigger pulls on hunting rifles?

Answer :

Final answer:

In target rifles, the trigger pull tends to be lighter and shorter for accuracy, contrasting with the often longer and heavier trigger pull of hunting rifles for safety. Military rifles have recoil-reducing mechanisms to minimize average force and improve precision. The force on a gun can be analyzed through recoil velocity, stopping force, and bullet acceleration comparisons.

Explanation:

Understanding Recoil in Rifles

When discussing the trigger pull for a target rifle to be used in a prone position compared to hunting rifles, the focus is on the precision and stability required for target shooting. In target rifles, the trigger pull is typically much lighter and shorter to allow for greater accuracy and less disturbance to the rifle's position. Conversely, hunting rifles might have a longer and heavier trigger pull for safety reasons, as they are often carried in potentially dangerous environments.

Military rifles feature mechanisms to reduce recoil, which are essential for improving accuracy and reducing fatigue for the shooter. Using a practical example, let's say we have a 1.00-kg plunger retreating with a 0.0200-kg bullet fired at 600 m/s. According to the law of conservation of momentum, the recoil velocity of the plunger would be determined using the formula: momentum of the bullet = momentum of the plunger, or (mass of bullet \\* velocity of bullet) = (mass of plunger \\* velocity of plunger). Solving the equation gives us the recoil velocity of the plunger. For stopping the recoil over a distance of 20.0 cm, the average force exerted by the gun on the plunger is calculated using the work energy principle, where the work done by the force is equal to the change in kinetic energy of the plunger.

In comparison, a bullet accelerated to its velocity in 10.0 ms would exert a different force on the gun, calculable by using the concepts of impulse and momentum change. A faster muzzle velocity could imply less bullet drop due to gravity and less need to compensate by aiming high, while air resistance would slow down the bullet and affect its trajectory.
