Cruiser Pulse cannons have say, 3k range? You could manouver to 3k, work on the shield and fire the missiles. If you keep up with the pulses, you'll drop the shield before the missile hit, scoring a hit on the hull.
Alternatively, if you want to use missiles against capitals, try aiming at the front of the ship. That's how nova torpedoes can be used against shielded caps - hitting them in the front somehow damages the shield.
