What could be wrong if I have chronographed the speed of my hand gun and it is not at the velocity it should be?
Different conditions will affect the chronographed speed of a handgun. The weight and shape of the pellet should be taken into consideration. A lighter pellet will increase the velocity. The above sea level altitude and temperature will also make a difference. Having all this in mind, it’s normal for a variation of 5-10% depending on conditions.
