I personaly have never tried it and i wouldn't.mainly because you want the bullet to "tweerl" smoothly as it traveles in the barrel.I thik this will happen only if either one "barrel or bullet" is rifeld not both,scince running two thrided surfecaes aginest each other will cause higher friction.
well i wonder if someone did tried it <img src=icon_smile_question.gif border=0 align=middle>
