There are various sorts of projectiles which can be mounted in the rail gun. These projectiles are shot out in high velocities. Because of these high velocities the shot goes through a gigantic measure of drag. This drag is the central issue for the shot’s effectiveness. This paper center around Round ball molded shot for electromagnetic rail gun and its working. The essential advantage of rail gun is a fired that can be pushed without using any engineered materials yet rather by using electric stream. It uses electromagnetic ability to ship off shots which are in between the two rails. A rail gun includes three segments a power source, several equivalent rails and a moving armature. A rail gun contains superconductive rails mounted agreed with each other with an in the center among them and is related with a DC supply. The shot gets speed through loathsome powers made by streaming current through equivalent rails. The driving of rail gun is achieved by changing over electrical energy into engine energy. The gun’s general not entirely set in stone by rail gun design, power supply and inductance point. In this investigation rail gun is arranged and cycles are performed to separate the current to launch a projectile at a speed of 2000 m/s with the distance between rails as 5 cm and 1000cm length
