magnetic rifling?

Instead of rifling, the barrel is smoothbore, with magnets
embedded in the walls to impose spin on the bullet

Ever heard of such a thing being investigated?

It would only work on steel, steel alloy, or steel cored bullets.

Varied technology uses the ideas and uses of magentics for braking systems and propulsion so I can see where magnetics could possibly be used in the physics of projectile firing.

Without goove and lans there would have to be another technology where there is sufficient friction and barrel contact so that there is pressure built up behind the bullet. However, if magnetics where properly used they could also be used in the propulsion stage of the firing process in addition to being used to spin and stabilze the bullet.

I saw a drawing of a proposed military artillary device using mag assisted shells, used a "starter charge" and shell acted as an initiator (brush) and became the armature of a linear motor, each section had electromagnets in series. Saw it in a popular science or mechanics.
as far as spin goes I think they could do better with fins, just look at what penetrator tank ammo can do.

It sounds like a rail gun:

only as far as having magnets. Railguns use the electromagnets for propulsion.

Yes.

I think anything using powerful enough magnets on that scale might as well use them the whole way. Could you imagine a big magnetic coil on your rifle barrell? Only existing railguns would have use for this, but it sounds like a natural development.
