The transonic effect related to spin-stabilised projectiles deals with the critical period of disruptive transition as the supersonic bullet reaches speeds close to the sound barrier.
#Benefits of subsonic bullet crack#
The supersonic crack however cannot be removed, and can be heard from quite a distance. When using a suppressor (or silencer) in conjunction with supersonic loads, the sound will still be obvious and audible, but the shot will make a dull thump rather than a loud bang, and locating the direction in which the shot originated from can be difficult. Precision rifle ammunition will fall into this category. Supersonic ammunition uses advanced aerodynamical projectiles with the perfect weight and shape designed to travel at high velocities and often over long distances. Stopping power is the firearm’s ability to cause a target to be incapacitated or immobilised through use of a penetrating projectile These high speeds which operate above the speed of sound drastically increase the bullet’s velocity and effective range, flattening its trajectory and increasing stopping power. This is a result of the sonic boom which occurs when the bullet breaks the sound barrier. Supersonic ammo cartridges are designed to operate at velocities greater than the speed of sound, which causes the bullet to make a “crack” as it travels downrange. Subsonic loads have a more unique purpose, and are typically custom loaded by hand or purchased for a very specific reason which we will discuss in more detail below.
These include the majority of pistol and rifle cartridges used for sports shooting, hunting and self defence.
The majority of gun owners, whether they know it or not, are familiar with supersonic cartridges. While subsonic ammo is quieter, producing less recoil, supersonic ammo produces a flatter trajectory, greater effective range and superior terminal performance (or stopping power) against living targets. In simple terms, subsonic means the bullet is moving slower than the speed of sound, while supersonic means the projectile breaks the sound barrier, producing a sonic crack as it travels through the air. While each have their own benefits, supersonic ammunition is most often the more responsible and ethical choice, specifically when related to hunting and defensive use. low speed ammo, and when one might be a more suitable choice over the other. Whether hunting, target shooting, experimenting with handloads or simply just curious, you may be wondering: what’s the difference between subsonic and supersonic ammunition, and which is better for your rifle? This article will cover what you need to know when comparing high vs.
