I'm curious too, and sadly don't have enough knowledge to even find answer on my own, how come superconductors can't be used as projectile for induction coilguns?

The biggest problem is that there are currently no known materials that superconduct above 92 kelvin. This is a problem in a weapon system, because the heat generated firing would make it exceptionally difficult to keep the projectile that cold through a long barrel.

What if you lined the inside of the barrel and the exterior of the superconducting projectile with some sort of insulating material? Will it last at least a millisecond?

the problem is that you are imparting so much kinetic energy directly to your projectile that you heat it up with the same induction forces that are propelling it. Imagine if you took an induction skillet and cranked enough current through it to fling the pan on top of it out your roof, that's what a coilgun does.
