a needle is light so easy to accelerate but that means that wind resistance would really affect it but could it be done whit reasonable range and damage an how good would it be as a weapon

Do some reading on flachette ammunition.
You could, it would probably not be that good.
You would need to carry a car battery or more around to power the thing. The power of the coil magnets is proportional to the current through them, so it might get fairly hot as well depending and might not have the rate of fire you’d want.
The ammo would be sharp and you would prolly hurt yourself when loading it numerous times.
be a cool toy though.
Hard to say! Coilguns are a balancing act on multiple axes, the needle would be fine probably, though it needs some drag or fins at the back so it doesnt tumble.
Heads up: with a 12V automotive air compressor, an empty sodastream bottle and a solenoid valve u can make a pretty heavy blowgun that can punch thru 10mm polycarb with some 2mm shafts ground to a point. Dont ask how i know this xD
Speed of sound is rather slow. The average rifle shoots a projectile many times heavier at 3x the speed of sound.
Accelerate a needle to the speed of light and it’ll go through a bunker (assuming you could find a material tough enough not to simply vaporize due to air resistance).
