I would:
1. calculate the time the bullet would take to get to the enemy.
2. calculate the speed the enemy is travelling at
3. figure out how much ground the enemy could make up, based on the time the bullet would take to hit it
4. extend the target in front of the enemy (using some sort of TFormPoint), using the distance worked out in step 3.
That should work. At least it does in my head :o)
