Based on how many turns you have on your coil, you have way to much inductance and the reactance is self limiting the current thus giving you a very slow discharge time. ALso it osunds like you are using very fine wire and that most likely cannot take the high currnet pulse and depending on the size of your projectile the long coil is actually slowing the projectile down. Instead of a single layer coil that is long "simiar to a tesla coil" you want a short but wide coil with much thicker wire. Read up on it in the coilgun wiki
