I have a custom tele i built and i have the samarium cobalt noisless pickups in them but when i use the bridge pickup it feeds back imediately? The neck is ok, but is this something i did wrong or what? I dont use distortion just some boost. If i use the middle or neck it fine? I dont get it. I thought the noisless werent supposed to do this?

Chances are your bridge pickup needs to be coil saturated and/or it is vibrating on the bridge plate which holds it.

That whistling and howling from your pickup is most likely due to the pickup's coil windings being loose and literally, picking itself up again in a loop as the sound comes out of your amp; hence, the feedback or to be more proper, The Larsen Effect.

Coil saturation, also known as, "potting" is the practice of immersing a pickup in a hot wax bath (4 parts paraffin wax to 1 part beeswax) at a controlled temperature in order for the wax to permeate the entire coil of your pickup. Once all the air bubbles have ceased, the pickup is then extracted and allowed to cool. What this does is it solidifies the coil and firms it up, thus preventing the Larsen Effect.

I don't recommend you trying it yourself as it could be dangerous. Most better techs are capable of doing this procedure for you.
