Yes, I know all that. When I said 'basic premise' I was referring to the
use of a magnetic field to accelerate the projectile, not the issues
surrounding the claimed muzzle speed.
Hollywood gets projectile momentum transfer wrong all the time. Every
time somebody gets shot by any kind of weapon, for a start.
