A drilling or cape gun with a 9.3 rifle barrel with a solid starts to sound very good in this situation.

As Miller stated, I would be less concerned with any damage to the gun.

Here is thread on AR on this very subject.

In short, it has been done, but I would not want to be around to witness the attempt.
