I have competed with bench rifles, and have learned the importance of free, or nearly free, recoil in consistency. But, it doesn't interest or amaze me nearly as much as a man who can hold that rifle so nearly the same every shot that he can put a bullet in the vitals at 1000 yards.
As I understand it, many snipers today are equipped with spotters who have a handheld programmable calculator that factors in all the variables and delivers the clicks necessary for the shooter to dial into the scope. More efficient, yes. And in war, efficiency is critically important. But, read
MARINE SNIPER, the story of Carlos Hathcock, for a riveting account of what the
man can do, unaided by technology. Not taking anything away from current snipers, they are still highly trained and skillful shooters and scouts.
For another wonderful account of a long range sniper read up on buffalo hunter Billy Dixon, and the Second Battle of Adobe Walls, on June 27, 1874. Dixon killed an Indian on a horse at nearly a mile, with a borrowed Sharps .50-90, with his third shot. Keep in mind that Furlong took two shots to kill the Taliban at about 800 yds. more, with the finest high tech equipment known to man. Not all long range kills are "one shot - one kill" events. Dixon was one of only 7 or 8 civilians ever to receive the Medal of Honor.
