TECHNOLOGY – RECOIL AND ACCURACY
Two phenomena that go together where shooting is concerned are the recoil of the gun and its accuracy. Finding the balance to get the best results is hard work, requiring knowledge and lots of testing.
According to our engineering and development department’s conclusions, the recoil of the spring and piston air guns, which makes their control more difficult and consequently the accuracy, results from the stiffness rate in the case of coil spring and the pressure curve in the case of gas springs (Gas Ram).
As for the gas ram, the pressure curve determines the effort to cock the air gun, the energy generated and the recoil, and the crucial point in obtaining the best performance of the air gun is to determine its application first, if for long range shots where Higher energy is required or for mid-range shots where the shooter prioritizes accuracy with less energy.
The pressure curve defines the type of use of the air gun, so a steeper pressure curve results in more energy and a flatter pressure curve results in less recoil, but also less energy and greater cocking effort.
As an example, a 40 kgf Gas Ram Air Rifle that generates 10 Joules has less recoil than a 35 kgf Gas Ram Air Rifle that also generates 10 Joules. This is because to generate the same energy of 10 Joules, the 40 kgf Gas Ram has a flatter pressure curve.
However, when the goal is to generate more energy, the pressure curve needs to be steeper, so it is possible to manufacture a 40kgf Gas Ram that generates 14 or 16 Joules, for example, but it will have a stronger recoil than the 40 kgf Gas Ram that generates only 10 Joules. Therefore, the conclusion is that the recoil is a result of the higher energy generated by the air gun. In these cases, we have air guns in the fast compression and slow compression system, also classified as blowpipe and popgun.
These phenomena occur in the same way with air guns equipped with coil spring. The difference is that in this case, the behavior of the air gun depends on the stiffness rate of the spring, which should not be confused with the modulus of elasticity, as these are different factors.
Thus, in the case of coil spring, the higher stiffness rate also causes faster compression and thus the recoil is stronger, while the lower stiffness rate results in less recoil of the air gun.
Therefore, it is necessary to apply the appropriate engineering knowledge to design and manufacture coil springs that meet the different conditions of use of the air gun, because, as we have said, long range shooting and hunting air guns where energy is the priority, act differently than the air guns used for target shooting at short or medium ranges where minimum recoil is expected.
However, for high-powered air guns, the effort to cock it can not be so strong, hence it is better to have a steeper curve of pressure that generates more energy but with less effort to cock the air gun, although it results in more recoil.
At QuickShot we are able to develop the Gas Ram or Coil Spring system that best fits the shooting conditions that every shooter seeks.
