But the raindrop is converted to vapor in a tiny explosion that will push on the bullet and deflect it ever so slightly, unless the bullet hits the raindrop absolutely dead center. The size of the explosion will depend on that of the raindrop, and on the temperature of the bullet. The result of the deflection will depend on the relative distance of the bullet between the muzzle of the gun and the target: the closer to the muzzle the "raindrop event" occurs, the farther off-target it will push the bullet.
All that said, I suspect that the actual effect would be, um, negligible.
