There are quite a few cases of this each year believe it or not.
Firearms expert Julian Hatcher studied falling bullets and found that .30 caliber rounds reach terminal velocities of 300 feet per second (90 m/s) and larger .50 caliber bullets have a terminal velocity of 500 feet per second (150 m/s).[8] A bullet traveling at only 150 feet per second (46 m/s) to 170 feet per second (52 m/s) can penetrate human skin,[9] and at 200 feet per second (60 m/s) it can penetrate the skull.[10] A bullet that does not penetrate the skull may still result in an intracranial injury
A musket ball would probably be around .50 if not bigger.
Yes but as we all know from physics, it is not the size nor weight of the object that necessarily defines its terminal velocity but the shape. A musket round is not particularly aerodynamic. Plus, unlike a 50 cal, it would not travel very high into the air (to acheive full terminal velocity on the way back down).
Musket ball
.50 calibre
The examples each year are generally people shooting "into" the air (but usually at an angle, however slight) which allows the bullet to keep its speed to an extent. The story above implies (as it must), a 90 degree shot into the air (for it to land in the same point) so its speed will have ceased at zero before descent.

Only passing on what i read, didnt the rebel leadership in the recent Libyan conflict ask the fighters to stop firing in the air as falling bullets were killing non combatants some distance away
Yes very possible but fired at angles. Not 90 degrees (to return to hit the shooter where the bullet passes through zero speed and returns of its own accord).
