"......Chris Kyle used a ..... but his 2,100- yard shot was on the third deployment, with the .338 Lapua magnum -- the longest kill shot on record.
The actual longest range sniper kill on record was a double by Corporal of Horse Craig Harrison of the Household Cavalry (British Army) in Helmand, Afghanistan, when he shot a Taliban machine gunner and then he killed the number 2, following which he put a round through their machine gun too, (to prove it wasn't a fluke) at a range of 2475m or 2707 yards. "
I don't know, but maybe Harrison's shots came after Jyle's. Records are meant to be brokem, after all. Regardless, some Soviet and Finnish snipers' kill numbers were upwards of 500, I understand, so Kyle's 150 (official) to 250 (his estimate, allegedly) kills pale in comparison. Anyway, these guys are all just doing their jobs and it's nothing they're particularly proud of, I suspect.
