Actually, a superconductor you could probably get a good few Tesla out of, but they're ceramic though and fragile.
There's no saturation with induction, presumably the only catch is you can't use iron in the circuit (well you can, but there's little point above 1.6 Tesla or so). The only saturation is when things get very hot. Oh yeah, and skin effect, you can't go too high frequency relative to the projectile.

Presumably there wouldn't be any point in using iron in the circuit, unless I'm misunderstanding something. I thought something similar about the saturation point; heating of the projectile might be desirable if you wanted to 'fling' high speed molten metal out
On another note I found this very interesting article which I would recommend reading:

Low speed coilgun efficiency (why it's so bad at high accelerations)
