Depending on your definition of sniping you could place it as early as the American Rebellion - units equipped with rifled guns were used to shoot important folks in the enemy formations (officers, artillerymen, etc). The British took this practice into the Napoleonic war (hands up who has read Sharpe) and both sides employed it in the war of 1812.
Since smokepole marksmen were mentioned: The Lone Marksman BTW, just reeived John Walter's Voices of Snipers which covers WW I & WW 2.
American rifleman Timothy Murphy famously killed (strictly speaking mortally wounded) British general Simon Fraser in one of the battles of the Saratoga campaign.
Paul Cheall of Fighting Through podcast reviews a sniper book from Casemate. 97 World War II Snipers - The Men, Their Guns, Their Story
Somewhere out there is a video a cousin sent me of a rifle that shot a bullet that actually turned a corner ?? I believe the projectile burst to the side and made a mess of the dude hiding around the corner?
Any idea where the energy came from to make it turn? Or was this a curving shot from the barrel? That might work.
It was some sort of rifle fired miniature missile, think 50 caliber size that spread shrapnel to the side at a set distance ?? this was 15-20 years ago. I'm not too sure of the accuracy but was interesting!

It appears Berdan wasn't held in high esteem. Hiram Berdan - Wikipedia. In the summer and fall of 1861, he was involved in the recruiting of eighteen companies, from eight states, which were formed into two sharpshooter regiments with the backing of General Winfield Scott and President Abraham Lincoln. Berdan was named as Colonel of the resultant 1st and 2nd U.S. Sharpshooters on November 30, 1861. His men, who had to pass rigorous marksmanship tests, were dressed in distinctive green uniforms and equipped with Sharps breech-loading rifles. Even when assigned to a brigade, the regiments were usually detached for special assignments on the field of battle. They were frequently used for skirmish duty. Berdan fought at the Seven Days Battles and Second Battle of Bull Run. In September 1862, his sharpshooters were at the Battle of Shepherdstown. Berdan commanded the 2nd Brigade, 3rd Division, 3rd Corps, Army of the Potomac in February and March 1863, then he commanded the 3rd Brigade at the Battle of Chancellorsville. Although Berdan was an innovative officer, as a leader he proved unpopular with the officers and soldiers under his command. In 1862, several of the sharpshooters' officers formally complained to General Daniel Butterfield, Berdan's immediate commander, that Berdan was both dishonest and a coward. In July 1862, General Fitz John Porter condemned Berdan as incompetent.[2]
For a while even though Berdan was defacto Colonel Commanding of the regiment, he did not hold a commission.
