I was toying with the coilgun I made a few weeks ago and got the idea of trying to use a coil wrapped projectile that would be pulsed in time with the main coil. Aside from the complex timing that would be required is this doable or has anyone tried it?

It seems you are describing a projectile wrapped in a coil, which is directly connected to a pulsed power source to attract / repel it from the main coil.
It sounds as if it would work, but a possible problem could be the actual connection of the projectile coil to the power supply.
Why not just make an induction gun? Then you could skip the direct connections, since the coil would act as a shorted transformer secondary and make its own repulsive field .
a spear gun is similar to this concept. The projectile coil is pulsed before its launched, but the magnetic field doesnt have chance to die away before it is fired (less than a ms after the pulse). I think 20% efficiency has been achieved using this method.
