I'm not saying that snipers didn't take long shots at distances of 800 yards but I am saying that if the sniper was aiming at the targets head and he actually hit it, it was a matter of luck.
Jim,
One requirement we know that American Ordnance held for the M 1855 and '61, etc. Rifle Musket was that it would be capable of "hitting a man size target at 600 yards and stopping the charge of a horse at 300 yards." Of course, they did not mean the rifle musket was capable of hitting the head of an enemy at that range, but somewhere on his entire body.
I don't know of any period source that shows what the Soldiers were taught to aim at.
My speculation from having fired many rounds at 500 yards at a man sized silhouette over many years, is that they did indeed aim at head because it was/is a finer aiming point to shoot at. It also is more or less in line with the center of the torso and that is important for possible windage aiming errors. However, I don't believe they expected to hit the head, rather the rounds would drop into the torso and be better centered side to side, ensuring a higher likelihood of hitting the torso. I know this technique worked the best for me and most other shooters on that silhouette target at 500 yards.
I also know that a man's head is distinguishable at 700 yards, even without the Shiny Brass device every Union Soldier wore on top of his Kepi. This from having watched many times from behind the 700 yard line that Scout Snipers have to hit a moving target in the body, 7 out of 10 times while the target is moving at a walking pace.
What I don't know is how much further the head is distinguishable, but it still would have been in their interest to aim at the top of the body for a finer aiming point and more of a chance of hitting the torso.

Modified to add: The aiming point at 500 yards that was most successful was where the bottom of the head/neck joined the shoulders on the silhouette target. It isn't quite that clear at 700 yards, but you can still aim at the head.
