RE: SG2, a little help with some weapon statistics

I was thinking that the atmospheric resitance channeled through the
rifeling
channels on the shell would impart the spin, rather than contact with
the
barrel. And, as you stated, magnetic or gravitic forces would provide
the
propulsion.

Hmm, rifling on a projectile implies contact with the barrel/launch
tube. I
assumed MDCs would not due to the nature of the magnetic propulsion
system.
Still, this same system could be used to rotate the projectile as well
as
move it forward?
