The maximum projectile range of a firearm is directly proportional to the characteristics of its bullet. These characteristics include weight, shape, and density of air. The more dense air is, the slower the bullet will move, decreasing the effective range of a firearm. But what factors actually affect a firearm’s maximum projectile range? We’ll discuss them in detail in this article.
One of the most important factors affecting the maximum range of a firearm is its elevation angle. For a five-inch gun, an Eg of 44 degrees 35 minutes is sufficient for a maximum projectile flight. However, if the elevation angle is increased by more than two degrees, the maximum projectile range of the firearm decreases significantly. In such a scenario, accurate estimation of the distance to the target is crucial, and this can cause missed targets.
Another important factor is the slope of a bullet’s trajectory. A shooting bullet tends to veer slightly off center from its point mass trajectory, but this effect is negligible at half range. Detailed analytical modeling and test range measurements can help determine the correct coefficients for a firearm’s maximum projectile range. However, the accuracy of the predictions depends on the angle of elevation, shooting location, and target.
For medium to long distances, these factors may become more important. However, for most hunters, these effects are not particularly relevant. The majority of firearms users, who use them in typical hunting situations, will find that they do not have a significant impact on their maximum projectile range. In these situations, normal group scatter has more influence. This article explains the differences between elevation angles and maximum projectile range.
As a result, knowing the maximum projectile range of a firearm is important when choosing a gun. If you have an errant shot, the bullet could travel a few miles before impacting the ground. If you know the maximum range of your firearm, you can assess whether you’re shooting safely. The table below shows representative figures for maximum projectile range of common rifle and handgun cartridges.
Pellet size is another key factor. Pellets range from “000” to a “9”, and a typical 9 mm shell has a KE of two hundred and fifty feet/lb. When compared to a shotgun shell, a 9 mm pellet has a lower kinetic energy and a lower dispersion pattern. But in contrast, a ten-millimeter bullet shot from a medium-sized handgun will travel more than two-hundred meters before hitting something.
Another factor that has a significant impact on a firearm’s maximum projectile range is wind. The wind causes a projectile to deflect in a horizontal and vertical direction. The wind’s force increases when a bullet shoots upwards while a bullet travels downward. Thus, wind velocity is the most important factor affecting maximum projectile range. However, there are some factors that can greatly reduce this effect.
