Very cool.  Brings back an old memory.  About 40 years I built a coil gun.  Nowhere near as sophisticated as the one in the Demolition Ranch video, though.  And not as powerful, either.  It launched a small steel rod only about 20 yards.

Apparently we are still well short of 556-esque energies but i think it could maybe be used to improve the accuracy of sabot rounds, by using magnets to 'centre' the bullet in the barrel

a steel barrel precludes the use of any coil. Besides, I cannot figure out what you mean with "center" the bullet in the barrel

Well if you could somehow hold it in thin air, by a magnetic force...then it would stay concentric, meaning you only need a sabot base to create a gas seal

It's really absurd and unfeasible. First of all, barrel is a continuous mass of steel

Second, the energy that you need to "hold in thin air" a bullet after another would require tens if not hundred of kg of equipment, batteries, etc.

third, catastrophic burst could happen for several reasons

I think that you didn't invest enough time in this concept.
