.22 Ammunition Feet Per Second Graph
In an effort to continue superior service to our customers, KIDD has compiled the following graph of popular ammunition to compare the feet per second (fps). The bold vertical line at 1126 fps denotes the speed of sound. This is important for our customers to know because if a bullet passes through the speed of sound barrier it becomes more unstable and the groups tend to spread out. The fps speed rating is determined with the assumption that it is being shot from a rifle barrel longer than 16 inches. If your bullet leaves the muzzle at supersonic and remains at supersonic to impact of target you will see very little if any negative effect on accuracy. However, if your bullet leaves the muzzle at supersonic and passes below 1126 fps prior to impact of target you will most likely see a deterioration of accuracy. Always stay above or below the speed of sound for optimum accuracy. Click Here to Save Graph.
