bullets traced to exact gun.

so ive been watching tv shows were bullets could be traced back to the exact gun used in shooting or crime. How does that work wouldn’t they need the gun that was used tho to track. or could they proceed with just a bullet

They can determine caliber fairly easily, they have the bullet that they recovered so they can just measure it. They take all the guns they think might be it and shoot them. They compare the marking on the bullets they fired to the one they recovered. Unless they already have your guns ballistics ( a sample stored at a local sheriff for ex) they must have your gun to do the tests to trace it to you. That’s why criminals ditch them in rivers.
